Settings

Generated by scripts/settings-reference.sh from rCommander's settings schema (crates/rc-engine/src/settings/), the settings dialog's pages and its texts; do not edit by hand. It cannot drift from what the program does: the same rows are the program's settings.

Every setting of the settings dialog (Configuration > Settings...), page by page in the dialog's order, with its key, the values it takes and its default. The key is the name an AI assistant uses with the MCP tools settings_get and settings_set (MCP server), and the name an exported settings file carries.

• Protected: only a person in the window changes it; settings_set refuses it for every caller, so an assistant never widens its own rights or chooses the programs and code that run.
• Restart: it takes effect the next time rCommander starts.

Appearance

Appearance > Theme and window

Setting	Key	Values	Default	Description
Language	appearance.language	One of Automatic (auto), English (en), Deutsch (de), Français (fr), Español (es)	Automatic	The language of menus, dialogs and messages. Automatic uses the language of Windows when rCommander has it, English otherwise. Restart.
Theme	appearance.theme	One of System (system), Light (light), Dark (dark)	System	Light or dark; System follows Windows, also when it changes while rCommander runs. Each mode draws with its theme (Themes tab).
Themes of connections and WSL distributions	appearance.connection_themes	On or off	On	A connection and a WSL distribution can each have a theme of their own for each mode (the connection in the connection manager, the distribution on the tab Themes): the panel - the list, the headers, the tabs - and its SSH or WSL terminal draw with it, so servers and distributions are told apart at a glance. Off: every panel draws with the window's theme; the connections and distributions keep theirs.
Show the function-key bar	appearance.function_key_bar	On or off	On	The row of F3 to F8 at the bottom of the window; the keys work either way.
Show the button bar	appearance.button_bar	On or off	On	The bar of buttons under the menu bar; Configuration > Button bar... changes its buttons.
Show the vertical button bar	appearance.vertical_button_bar	On or off	Off	A second bar of buttons between the two panels, as Total Commander's Button Bar 2.
Bar above the panels	buttonbar.horizontal	A whole number from 0 to 2147483647	0	The id of the bar the button bar shows; 0 shows the first. Use as button bar in the button bars' window sets it.
Bar between the panels	buttonbar.vertical	A whole number from 0 to 2147483647	0	The id of the bar the vertical button bar shows; 0 shows the first.
Size of the button symbols	buttonbar.icon_size	One of 16 pixels (16), 24 pixels (24), 32 pixels (32)	24 pixels	The side of a button's symbol, in pixels.
Show the drive buttons	appearance.drive_bar	On or off	On	The bar of drive buttons above the panels; the drive line under it stays.
Show the command line	appearance.command_line	On or off	On	The command line under the panels.
Show the status bar	appearance.status_bar	On or off	On	The line at the bottom of the window with the MCP server, the jobs and the news.
Menu bar	appearance.menu_bar	On or off	On	The menu bar at the top of the window, opened with Alt and a menu's underlined letter. Without it every command keeps its key and its row in the command palette (Ctrl+Shift+P).
Menu bar style	appearance.menu_bar_style	One of In the theme's colours (drawn), Windows menu (native)	In the theme's colours	How Windows shows the menu bar: drawn by rCommander in the theme's colours, or the Windows menu, which knows only light and one dark grey. Alt with a menu's underlined letter opens a menu either way. Changes at once.
Mac look on macOS	appearance.macos_look	On or off	On	On: macOS's greys for light and dark mode with the accent chosen in System Settings, San Francisco and Menlo as fonts, and a transparent title bar over the window. Off: the look rCommander has on Windows and Linux, with the system's title bar. The menus stay in the system's menu bar either way. Only on macOS. Restart.
Dialogs in windows of their own	appearance.dialog_windows	On or off	On	When on, the dialogs open in windows of their own that you can move and resize; each opens where you left it. That is the connection manager, find files, multi-rename, compare/synchronize, the checksum results, the login-script editor and Lister, the smaller dialogs: backup, restore, export and import, properties, quick connect, network drives, pack and unpack, the checksum forms, the directory hotlist and Run command, the file operations: copy, move, new folder or file, delete, their questions and the progress window, and the small questions: an agent's call, host keys and certificates, the vault, quitting, an archive's password, a large download and synchronizing. Multi-rename, the smaller dialogs, the file operations and the questions (but synchronizing's, which waits only for its window) keep the main window waiting; beside the others you can work on in the main window. When off, they open over the main window.
Ask to restart when the graphics are lost	appearance.gpu_loss_notice	On or off	On	When on and the graphics card loses its device (a driver reset, standby, a change of GPU), rCommander can no longer draw; a message box asks whether to restart it. Tabs and places are kept, transfers continue at the next start. When off, the window stays as it is until you close it.

Setting	Key	Values	Default	Description
Switch to a column set by folder	columns.auto_switch	On or off	On	A panel entering a folder that a column set's folder mask matches shows that set; the first set in the list wins. A view chosen by hand stays until a folder of another set.

Appearance > Viewer

Setting	Key	Values	Default	Description
Show Markdown files as a preview	viewer.markdown_preview	On or off	On	Lister (F3) and Quick View (Ctrl+Q) show a .md or .markdown file formatted; 5 switches between the preview and the text. Off: such files open as text, and 5 still shows the preview. Images are never loaded, HTML in the file is shown as text, and only http, https and mailto links open, on a click.
Select and copy in the Markdown preview	viewer.markdown_select	On or off	On	The mouse selects text in the preview, also across paragraphs, lists, tables and code; Shift+click extends, a double click takes a word, a triple click a line. Ctrl+A selects all, Ctrl+C copies the selection as plain text. Applies to files opened afterwards.
Colour code blocks in the Markdown preview	viewer.markdown_code_highlight	On or off	On	A code block whose tag names a language (```rust, ```json, ```sh, ```python, ```sql and other common ones) shows keywords, strings, numbers and comments in the theme's colours. A block without a tag or with an unknown one stays plain; a block over 64 KiB stays plain. Applies to files opened afterwards.
Largest picture shown at full detail (megapixels)	viewer.picture_megapixels	A whole number from 4 to 256	32	A picture with more pixels is scaled down to this many before it is shown, so a very large photo or scan opens without using gigabytes of memory; zoom and the status line still go by its own size. Higher is sharper when you zoom in.
Open as DOS text (code page 437)	viewer.dos_extensions	File extensions without dots, separated by spaces	nfo diz	File extensions without dots, separated by spaces. Lister (F3) and Quick View (Ctrl+Q) show such files in the DOS character set, with its box-drawing art, and without wrapping; a file with a byte-order mark, in UTF-16 or in UTF-8 beyond plain ASCII keeps its own encoding. In the viewer S switches to DOS and A back to ANSI. Empty: no file opens as DOS text.
Let the blocks of DOS art touch	viewer.dos_tight_lines	On or off	On	DOS text - an .nfo, a .diz, or any file switched to DOS with S - draws its lines exactly as tall as the viewer font's full block, so the block characters of its art join without gaps, as in Total Commander's Lister. Off: its lines are as tall as any other text's.
Ctrl+wheel, Ctrl++ and Ctrl+- change the viewer's text size	viewer.text_zoom	On or off	On	In Lister (F3) and Quick View (Ctrl+Q) the text, binary, hex and Markdown views get a step larger or smaller, from 6 to 72 points; Ctrl+0 goes back to the viewer font size. In the image view the same keys zoom the picture and Ctrl+0 fits it to the window. Off: Ctrl+wheel scrolls, and in Quick View Ctrl+Num+ and Ctrl+Num- select and deselect all as in the panels.
A changed text size	viewer.text_zoom_keep	One of Applies to this viewer window only (window), Is saved as the viewer font size (setting)	Applies to this viewer window only	This window only: the size stays with that viewer window and the files N and P step to, or with Quick View while its cursor moves; the next viewer opens at the viewer font size. Saved: every change is stored as the viewer font size, so every viewer opens at it, and Ctrl+0 stores the default 13.
Show a photo's EXIF beside the picture	viewer.exif	On or off	On	Lister (F3) and Quick View (Ctrl+Q) offer the EXIF of a JPEG, PNG or WebP photo - camera, exposure, date, position - as a second view beside the picture; 7 switches between them. Only the EXIF block is read. Off: a photo shows the picture alone.
N and P step through the marked files	viewer.step_through_selection	On or off	On	F3 with marked files: Lister steps only through those; Shift+F3 shows the file under the cursor alone.
Show certificates and keys with their checks	viewer.certificates	On or off	On	Lister (F3) and Quick View (Ctrl+Q) show a certificate, certificate request or key file (PEM, DER, OpenSSH, authorized_keys) as its checks and objects - validity, chain, whether a key belongs to its certificate, weak keys and signatures - as text and, on 7, as a tree. A private key is shown only by its type, size, encryption and fingerprint, never decrypted. Off: the file shows as it is.
Warn this many days before a certificate expires	viewer.cert_expiry_warning_days	A whole number from 0 to 365	30	A certificate whose end is fewer days away is a warning in the certificate view's checks; 0 never warns.

Appearance > Thumbnails

Setting	Key	Values	Default	Description
Tile size	thumbnails.size	A whole number from 32 to 512	96	The side of a thumbnail in pixels, 32 to 512 (96 as in Total Commander). Ctrl and the mouse wheel over the thumbnails change it in steps.
Keep thumbnails on disk	thumbnails.disk_cache	On or off	On	Thumbnails of local files are kept in your cache folder, so a folder shows them at once the next time. Files on servers, devices and in archives never go there.
Disk cache size (MiB)	thumbnails.cache_mb	A whole number from 16 to 4096	256	16 to 4096. At the start the thumbnails used longest ago go once the cache is larger.
Thumbnails on servers, devices and in archives	thumbnails.remote	On or off	Off	Off: files over SFTP and FTP, on phones and inside archives show their icon, and nothing is read for a thumbnail. On: pictures up to 32 MiB are read whole; their thumbnails stay in memory only.
Explorer's thumbnails for other files	thumbnails.explorer	On or off	Off	PDFs, videos and documents get the thumbnail Explorer shows. This runs the thumbnail handlers other programs installed inside rCommander, on every file you look at. Off, those files show their icon.

Folders

Setting	Key	Values	Default	Description
Left panel starts in	folders.left_start	An absolute path	empty	An absolute folder; empty for the home folder. A folder that is missing at the start counts as empty. Restart.
Right panel starts in	folders.right_start	An absolute path	empty	An absolute folder; empty for the home folder. A folder that is missing at the start counts as empty. Restart.
Calling up a workspace	workspaces.apply_mode	One of Replace all tabs (replace_all), Replace the tabs, keep locked ones (replace_keep_locked), Add the tabs (add)	Replace all tabs	What a workspace does to the tabs a panel has when you call it up (Ctrl+Shift+W, the command palette, its own key): its tabs replace all of the panel's (the default); its tabs replace the panel's and locked tabs stay; or its tabs come after the panel's. A folder the panel shows already is not opened a second time. Terminals of the same kind that run already are reused.
Workspace at the start	workspaces.on_start	A short name: letters, digits, ., _ and -	empty	The workspace rCommander calls up when it starts, by its id, after the tabs of the last run came back; empty for the last run's tabs alone. A start folder forced with RC_START_DIR wins. Takes effect at the next start. Restart.
Keep the file filter separately for each tab	tabs.filter_per_tab	On or off	On	On, each tab keeps the file filter of Ctrl+F10, Ctrl+F11 and Ctrl+F12; off, the tabs of a panel share one, as in Total Commander before version 10.
Ask before closing all tabs	tabs.confirm_close_all	On or off	On	Close all tabs from a tab's menu or the menu Commands asks whether the locked tabs close too; off, it closes the unlocked ones at once.
Most visited folders in the history list	history.frequent_shown	A whole number from 0 to 50	10	How many of the most visited folders Alt+Down lists below the folder history; the counts halve every 30 days. 0 shows none and counts nothing.
Programs (Ctrl+F11)	filters.programs	File extensions without dots, separated by spaces	exe com bat cmd pif	The extensions Ctrl+F11 shows as programs, separated by spaces. Outside Windows a file with an execute bit is a program too.
Use the ignore list	ignore_list.enabled	On or off	Off	On, the names and paths of the ignore list never show in the file lists, the flat views, the search and the folder sizes, and copies and moves leave them where they are; deleting a folder names how many it holds.
Ignore list	ignore_list.entries	Lines, one entry each: a name or a mask (*.bak), a path (%USERPROFILE%\AppData), \Path on every drive, a \ at the end for folders only; at most 1000 lines	empty	One entry per line: a name or mask (*.bak) hides it in every folder; a path (%USERPROFILE%\AppData) hides that folder on this computer; \Path without a drive on every drive; a \ at the end only folders. At most 1000 lines.
Quick search starts with	quick_search.keys	One of Ctrl+Alt with letters (ctrl_alt), Alt with letters (alt), Letters alone (letters)	Ctrl+Alt with letters	Ctrl+Alt with letters searches and letters alone go into the command line. With letters alone, typing searches; the command line then takes text after a click into it.
Quick search matches anywhere in a name	quick_search.anywhere	On or off	Off	Off: a name must start with the typed text. * and ? work as wildcards either way.
Quick search tells upper from lower case	quick_search.case_sensitive	On or off	Off	Off: report and Report match alike.
Quick search hides what does not match	quick_search.filters	On or off	Off	On: the quick search shows only the files and folders that match, as the filter (Ctrl+S) does; Enter keeps it, Escape shows everything again. Off: it only moves the cursor to the match.
Find files starts with Search archives ticked	search.archives_default	On or off	Off	On: Alt+F7 opens with Search archives ticked, so zip, 7z and tar files on local drives are searched like folders. Each search can still change it.
Find files offers Everything	search.everything	On or off	On	On: where Everything (voidtools, 1.4 or later) runs, Find files offers to take its candidates from Everything's index, also with ev: before the masks. Windows only.
Disk usage shows	disk_usage.size	One of Bytes of the files (bytes), Space occupied on the volume (allocated)	Bytes of the files	What the disk-usage window (Ctrl+Shift+L) shows and sorts by: the bytes of the files, or what they occupy on the volume where the file system tells it (a dash elsewhere).
Largest files listed	disk_usage.largest_files	A whole number from 10 to 1000	100	How many of the largest files the disk-usage window keeps on its second tab (10 to 1000).
Enter opens archives	archive.enter_opens	On or off	On	On: Enter on a .zip, .7z or .tar file shows its contents in the panel. Off: the system opens it. Ctrl+PageDown always opens an archive in the panel.
Archive decoder memory (MiB)	archive.decoder_memory_mib	A whole number from 16 to 4096	256	The most memory unpacking an .xz, .tar.xz or .7z file may set aside for its dictionary. A file whose header asks for more is refused before anything is reserved, so a crafted archive of a few bytes cannot take gigabytes. 256 MiB is more than any xz or 7-Zip preset uses. Counts for archives opened from now on.
Check a changed archive	archive.verify_after_update	On or off	On	On: after files are added to an archive or removed from it, the new archive is read back before it replaces the old one; if it does not read back, the old one stays. Off saves the second read of a large archive.
Enter verifies checksum files	checksum.enter_verifies	On or off	On	On: Enter or a double click on a .sfv, .md5, .sha, .sha1, .sha256, .sha512, .b3 or .blake3 file checks the files it lists. Off: the system opens it. Ctrl+Shift+F10 always checks it.
Num+, Num- and Shift+F2 select folders too	selection.include_folders	On or off	Off	On: Num+ and Num- also select and deselect folders whose names fit the mask (*.* takes every folder), and Shift+F2 also selects the folders only one side has. A mask ending in \ always means folders only.
Space moves the cursor to the next entry	selection.space_moves_down	On or off	On	On: Space selects the entry under the cursor and moves on to the next one, as Insert does. Off: the cursor stays on the entry. A folder is counted either way.
A click clears the selection (as in Explorer)	mouse.click_clears_marks	On or off	Off	Off: a click in a file list only moves the cursor and the selection stays, as in Total Commander. On: a click also clears the selection, as in Windows Explorer. Ctrl+click and Shift+click select either way.
Drag tabs to reorder them	tabs.drag_reorder	On or off	On	On: a tab dragged within its tab bar goes where it is dropped, as in Total Commander; a click still shows it, Escape cancels the drag. Off: a press on a tab only shows it. In the list of tabs (Ctrl+Shift+A) Ctrl+Up and Ctrl+Down move a tab either way.
A drive change goes to the other panel's folder	drives.follow_other_panel	On or off	On	On: changing to the drive the other panel shows (drive bar, drive menu, or a drive letter in the command line such as d:) opens the other panel's folder, as in Total Commander. Off: the folder this panel last showed on that drive, else the drive's root.
A drive letter in the command line (such as d:) follows the other panel on the same drive too	drives.follow_on_own_drive	On or off	On	On: a drive letter in the command line (such as d:) opens the other panel's folder even when this panel is already on that drive, at another folder, as in Total Commander. The drive bar and the drive menu leave a panel on its own drive where it is. Works only while "A drive change goes to the other panel's folder" is on.
Read the panels again on return to the window	panels.refresh_on_focus	On or off	On	On: when you come back to rCommander from another program, every panel that shows a folder on a local drive or a WSL distribution is read again, so a file saved meanwhile appears. Cursor, selection and scroll position stay. Switching between rCommander's own windows reads nothing again. Servers and archives are never read again this way.
Also network drives and shares	panels.refresh_on_focus_network	On or off	Off	On: the return to the window also reads panels on mapped network drives and network shares (\\server\share) again. Off by default, since a slow server would be asked on every return. Works only while "Read the panels again on return to the window" is on.
Show portable devices in the drive bar	drives.portable_devices	On or off	On	On: phones, tablets and cameras connected over USB (MTP) appear in the drive bar under their own name; their files can be read, copied both ways and deleted, and new folders created on them. Off: the system is not asked for them.
Git status in the file lists	panels.git_status	One of Off (off), Local drives (local), Also network drives (local_network)	Off	Where rCommander runs git to mark changed, new and ignored files and to show the branch. Off (the default) runs git nowhere; Local drives on fixed and removable drives and in WSL distributions (only while the distribution runs); Also network drives adds network drives and shares. git runs only for a folder inside a repository, hardened against the repository's own configuration: no filter driver (Git LFS among them) and no fsmonitor runs, so an LFS file whose time changed may show as modified. Needs git 2.36 or newer. Only you can switch this on; an agent cannot. Protected.
Dim the files git ignores	panels.git_ignored	On or off	On	On: entries a .gitignore excludes are drawn dimmed. Off: git is not asked for them, which is quicker in large repositories.
Git branch in the status line	panels.git_branch	On or off	On	On: a panel's status line shows the repository's branch with the commits ahead of and behind its upstream, or HEAD and the commit when it is detached.
Read the panels again when their folder changes	panels.watch	On or off	Off	On: a folder shown in a panel is watched, and a file created, deleted or renamed in it appears within about a second, as Total Commander's automatic refresh does. Cursor and selection stay. Only folders on this machine are watched; archives, servers and search results are not. Off by default.
Also when size, date or attributes change	panels.watch_changes	On or off	Off	On: a file that only grows or gets a new date also reads the panel again. Off by default, since a download in progress would read the panel over and over.
Also network drives and shares	panels.watch_network	On or off	Off	On: folders on mapped network drives and network shares are watched too. Off by default, since some servers keep a connection open for each watched folder or stop reporting without notice.
Drives never watched	panels.watch_exclude	Drive letters such as DE; a backslash stands for every network share (UNC path); empty for none	empty	Drive letters such as DE, and a backslash (\) for every network path (\\server\share). Empty: every drive is watched.
Read while another program is in front	panels.watch_background	On or off	On	On: changes are shown while you work in another program. Off: a change is only noted, and the panel is read once when you come back.
Read the panels again when a terminal command ends	terminal.refresh_panels_on_prompt	On or off	On	On: when the shell of a local or WSL terminal is back at its prompt after a command, the panels showing local folders are read again, so a file the command made appears. Works without the file watcher; needs the shell integration. SSH terminals never read the panels.
Tree: Enter opens the folder in the panel	tree.open_on_enter	On or off	Off	Off, a panel shows the folder under a tree's cursor once the cursor rests for a moment; on, only after Enter or a double-click, as Total Commander's option.
Sort names	sort.names	One of Like Windows (Total Commander) (windows), Like Linux (byte order) (linux), By the panel's target (by_target)	Like Windows (Total Commander)	Like Windows and Total Commander: upper and lower case alike, symbols before digits before letters, hyphens and apostrophes only between otherwise equal names. Like Linux: the byte order of ls in the C locale, capitals first. By the panel's target: Windows' order on this computer's drives, Linux' on SSH and FTP servers and inside WSL.
Sort numbers by their value	sort.numbers_by_value	On or off	On	On: file2 comes before file10, as in Total Commander and the Explorer. Off: digits compare as characters, file10 before file2.

Keyboard

Setting	Key	Values	Default	Description
F10	keys.f10	One of Closes dialogs, quits without one (close_and_quit), Closes dialogs only (close_dialogs), Does nothing (off)	Closes dialogs, quits without one	With a dialog open, F10 closes it as Esc does; with none open it quits rCommander. In a terminal panel F10 belongs to the shell.
Always underline access keys	keys.underline_access_keys	On or off	Off	On: the underlined letters of the dialogs' buttons always show. Off: they show while Alt is held, as in Windows. Alt with the letter presses the button either way; the letter alone does while a button or checkbox has the focus ring.
Show keys in context menus	keys.context_menu_shortcuts	On or off	On	On: the menus rCommander draws - a tab's, the file list's own, the queue's - show each entry's key on the right, as Windows menus do. Off: the entries' names only.
The connection manager opens in its list, on the connection used last	connections.focus_list	On or off	On	When on, Ctrl+F opens the connection manager with the keyboard in the list and the cursor on the connection you used last, so the arrow keys and Enter choose at once; a letter typed there goes into the filter. When off, the keyboard starts in the filter field.
Cmd works as Ctrl on macOS	keys.macos_cmd_as_ctrl	On or off	On	On: Cmd does what Ctrl does in the keymap (Cmd+R refreshes, Cmd+Shift+P opens the command palette), Ctrl still works, and keys show with the Cmd symbol. Off: only Ctrl is Ctrl, a key pressed with Cmd is left to the system, and keys show with the Control symbol. Only on macOS.
Shortcuts	keys.overrides	Pairs key=command, separated by spaces; key= takes a standard key away	empty	Your changes to the standard keys, as the Shortcuts tab writes them: Ctrl+K=copy gives Ctrl+K the copy, F5= takes F5 away, Ctrl+1=theme:dark:nord-dark switches to the dark Nord theme. The standard keys: Keyboard shortcuts. Protected.

Terminal

Setting	Key	Values	Default	Description
Default shell	terminal.default_shell	A short name: letters, digits, ., _ and -	empty	The shell a new terminal session runs; when it is not installed, the first shell found.
Terminal follows the panel	terminal.follow_panel	On or off	On	Turning to the terminal, or moving the panel while it shows the terminal, changes the shell's folder too - only while the shell waits at an empty prompt, never into a running program.
Panel follows the terminal	terminal.panel_follows	On or off	On	Turning back to the files shows the folder the shell was last in.
Shell integration	terminal.shell_integration	On or off	On	New shells (PowerShell, bash, zsh, cmd) report their folder and prompt to rCommander; without it neither direction follows. Applies to shells started from now on.
Warn when a login script types a secret without a password prompt	login_scripts.warn_secret_prompt	On or off	On	The login-script editor marks a Send secret step whose step before does not wait for a password prompt: the secret would be typed into whatever waits there, a shell too, and could end up in its history.
End programs started in a terminal with it	terminal.end_programs_on_close	On or off	On	On, closing a terminal - or rCommander - also ends what its shell started, such as ssh, a build or a window opened from it, so nothing keeps running unseen. Off, only the shell ends and programs started from it keep running. Windows; elsewhere closing the terminal hangs them up.
Ctrl+C copies selected text	terminal.copy_ctrl_c	On or off	On	On, Ctrl+C copies the text selected in a terminal and clears the selection; with nothing selected it interrupts the running program as always. Off, Ctrl+C always interrupts; Ctrl+Shift+C copies either way.
Right click copies selected text	terminal.copy_right_click	On or off	On	On, a right click copies the text selected in a terminal and clears the selection; with nothing selected it pastes (Windows). Off, a right click always pastes.
Copy text as soon as it is selected	terminal.copy_on_select	On or off	Off	On, letting go of the mouse after selecting text in a terminal copies it at once. Off, selected text is copied with Ctrl+C, Ctrl+Shift+C or a right click.
Ctrl+V pastes text	terminal.paste_ctrl_v	On or off	On	On, Ctrl+V pastes the text on the clipboard into a terminal; with no text on it - an image, say - Ctrl+V goes to the running program, which may paste the image itself. Off, Ctrl+V always goes to the program; Ctrl+Shift+V and a right click paste either way.
Programs may copy to the clipboard	terminal.osc52_copy	On or off	On	On, a program in a terminal - also on a server you are connected to - may put text on the clipboard (OSC 52), as Claude Code does with what you select in it. Programs can never read the clipboard this way. Off, such copies are dropped.
Programs on a server may copy to the clipboard	terminal.osc52_remote	On or off	On	On, a program in an SSH terminal may put text on the clipboard too (OSC 52), as in Windows Terminal. Off, only the programs of local and WSL terminals may. Either way only the terminal a panel shows sets the clipboard, with at most 1 MiB of text, and the status line says which one did.
Shift with the mouse selects text	terminal.shift_selects	On or off	On	On, holding Shift while you select with the mouse selects text in the terminal even when a program such as Claude Code or vim takes the mouse; Ctrl+C or a right click then copies it. Off, the mouse always goes to such a program.
Ctrl+Alt+V pastes an image as a file path	terminal.paste_image	On or off	On	On, the key (Ctrl+Alt+V unless changed in Shortcuts) saves the clipboard's image as a PNG file where the terminal's program can read it - the temp folder, the same file under /mnt for WSL, /tmp on an SSH server, uploaded without asking - and pastes its path, for Claude Code and other programs that read images from a path. The files are removed when the terminal closes. Off, the key does nothing.
Most agent keys offered per login	ssh.agent_max_keys	A whole number from 1 to 20	5	How many keys of the SSH agents one login offers, the connection's own key first. A server counts each key against its limit of tries and learns every key offered (1-20). Protected.
Use OpenSSH certificates at the SSH login	ssh.certificates	On or off	On	A certificate your CA signed for a key is offered before the key itself: the one stored with the key, the certificate file beside a key file (its name with -cert.pub), and those an SSH agent holds. Importing a key also takes the certificate beside it. Off, keys log in alone and the agents' certificates are passed over. Protected.
Answer one-time code questions at the SSH login	connections.totp_autofill	On or off	On	When a connection has a one-time code seed, rCommander answers the server's question for a verification code with the current code. Off, the question is left unanswered, as without a seed; a login script's Send one-time code step still sends it. Protected.
Allow port forwards from other computers	ssh.forwards_lan	On or off	Off	Lets a port forward listen on 0.0.0.0, :: or another address of this computer, which other computers reach and which the firewall asks about. Off, such a forward does not start. Protected.
Reconnect port forwards after a lost session	ssh.forward_reconnect	On or off	On	On, the next connection through a forward connects its session again; off, a lost session stops its forwards.
Show running port forwards in the status bar	ssh.forwards_in_status_bar	On or off	On	"Forwards: n" while some run; each one in its tooltip.

Vault

Setting	Key	Values	Default	Description
Lock the vault after minutes without use	vault.idle_lock_minutes	A whole number from 0 to 1440	15	0 never locks. Locked, stored secrets need the master password again. Protected.
Lock the vault at the latest after hours unlocked	vault.max_unlocked_hours	A whole number from 0 to 168	8	Counted from the unlock, however often it is used. 0 sets no limit. Protected.
Lock the vault when Windows locks or goes to sleep	vault.lock_on_session_lock	On or off	On	Win+L, the lock screen, sleep and hibernation lock the vault. Protected.
Offer the Windows Credential Manager as a secret source	vault.wincred_source	On or off	On	A connection can take its password from a generic entry of the Windows Credential Manager, read at every connect. Only on Windows; rCommander never changes the entries. Protected.
Let connections use shared credentials	vault.shared_credentials	On or off	On	A shared credential keeps a user, password, key and passphrase once in the connection manager, and any number of connections can use it. Off, every connection uses its own again and the manager offers no credentials. Protected.
Keep the checkout reason for later connects	vault.checkout_keep_reason	On or off	On	A reason given for a PAM system's checkout goes with the connection's later checkouts until rCommander ends. Off, every checkout asks for a new one. Protected.

MCP server

Setting	Key	Values	Default	Description
MCP server on	mcp.http.enabled	On or off	On	Off, agents reach rCommander neither over HTTP nor through rcommander mcp. Protected.
Port	mcp.http.port	A whole number from 0 to 65535	0	The port on 127.0.0.1; 0 picks a free one. The server restarts on the new port at once. Protected.
Allow confirmation codes without a window	mcp.ask.headless_code	On or off	Off	When rCommander is not running, rcommander mcp has nobody to ask. Off, every tool that asks is refused there; on, the agent gets a one-time code and is told to ask you - but nothing proves you saw it. Protected.
Minutes an executing call stays allowed	mcp.ask.exec_session_minutes	A whole number from 0 to 480	30	"Allow here for ... min" lets an agent keep typing into the same terminal or running commands on the same server for this long without asking again; another terminal or server still asks. 0 never offers it. The status bar shows what is allowed; a click there takes it back. Protected.
Ask before reading or writing outside the panels' folders	mcp.ask.outside_panels	On or off	Off	On, a reading or writing tool asks you first when a file or folder it names lies outside the two folders the panels show - wherever links lead. Off, the agent reads and writes where the policy allows; keys, credential files and start-up files stay refused either way. Protected.
New token at every start	mcp.token.rotate_on_start	On or off	Off	On, each start of rCommander gives the MCP server a new access token, so a token copied before stops working; rcommander mcp picks the new one up by itself. Off, the token stays until you make a new one - an HTTP client configured with it keeps working. Protected. Restart.
Record the agents' calls	mcp.audit_log	On or off	On	On, every tool call an agent makes is kept in the list below with what rCommander decided, its arguments masked. Off, nothing is recorded. Protected.

Programs

Setting	Key	Values	Default	Description
Viewer (F3)	files.viewer	An absolute path	empty	An external program for F3. Empty: rCommander's own viewer. Protected.
Editor (F4)	files.editor	An absolute path	empty	The program F4 and Shift+F4 open a file with. Empty: Notepad. Protected.
Git program	panels.git_program	An absolute path	empty	The git that marks the file lists. Empty: the first git in the folders of PATH (absolute ones only), on Windows then Git for Windows in Program Files. In a WSL distribution its own /usr/bin/git runs. Only you can change this; an agent cannot. Protected.
Internal associations	files.associations	The internal associations as a JSON list of rules, edited in the window Internal associations...; empty for none	empty	Commands by file type that Enter and the context menu run ahead of the system's association; F3 and F4 do not use them. Protected.
Use the internal associations	files.associations_enabled	On or off	On	Off: Enter and the context menu use the system's association alone. Protected.
Load extra commands from all matching types	files.associations_all_matches	On or off	Off	The context menu offers the named commands of every rule whose mask matches, not only the first's. Protected.
After a server file opened for editing is saved	remote_edit.upload	One of Ask (ask), Upload without asking (auto)	Ask	F4, Enter and an external viewer on an SFTP, FTP or FTPS file open a local copy, watched for saves. Ask: each save asks whether to upload it (with a box to stop asking). Upload without asking: each save goes to the server at once, as Total Commander's "Automatically re-upload changed files". Protected.
Check the server's file before an upload	remote_edit.check_server_changes	On or off	On	Before a copy goes up, the file on the server is looked at: if its size or time changed since it was opened, or it is gone, you are asked first - Overwrite, Upload as copy or Not now. Protected.
Enter opens programs on a server	remote_edit.open_programs	On or off	Off	Off, Enter refuses a server file that would run as a program (an extension of PATHEXT on Windows, an execute bit elsewhere): copy it first (F5). On Windows every fetched copy is marked as coming from the internet either way. Protected.
External compare program	compare.external_tool	An absolute path	empty	Compare by content (Ctrl+Shift+F3), the Compare button of the overwrite question and a row of Synchronize directories start this program with the two files instead of the diff window - such as WinMerge, Beyond Compare, Meld, KDiff3 or opendiff. Shift held at the click opens the diff window anyway. Empty: the diff window. Protected.
Arguments of the compare program	compare.external_args	A program's arguments: words, double quotes round one with spaces; %1 is the left file, %2 the right one	"%1" "%2"	%1 is the left file, %2 the right one; double quotes keep spaces in one argument, and no shell reads them. Files on a server or in an archive go as read-only copies. Protected.

Transfers

Setting	Key	Values	Default	Description
Copy buffer (KiB)	transfers.buffer_kib	A whole number from 16 to 16384	256	How much of a file one read and one write move, for copies and moves on this machine and to and from servers. Counts from the next copy.
Transfers at once per server	transfers.per_connection	A whole number from 1 to 8	2	How many copies and moves to or from one server run at the same time; the others wait in the queue.
Transfers at once in all	transfers.max_running	A whole number from 1 to 16	4	How many copies and moves run at the same time altogether; a drive on this machine always takes one at a time.
Retries after a lost connection	transfers.retry_count	A whole number from 0 to 10	3	How often a copy or move to or from a server tries again when the connection breaks, each time continuing the file where it stopped. Then the job pauses and waits for Resume; 0 pauses at once.
First wait before a retry (seconds)	transfers.retry_delay_secs	A whole number from 1 to 300	5	How long a transfer waits before its first retry after a lost connection; each further wait is twice as long.
Ask before quitting while transfers run	app.confirm_quit_with_transfers	On or off	On	Quitting with F10, the window's close button or Alt+F4 while copies, moves or other jobs run or wait asks first. The queue is kept and continues at the next start either way.
Delete for good where there is no recycle bin	delete.permanent_without_trash	On or off	Off	Servers, network shares and WSL folders have no recycle bin. When on, F8 and Delete there ask to delete for good, as Shift+Delete does. When off, they delete nothing there and say so; Shift+Delete deletes for good.
Links to folders	ops.copy_links	One of Copy the folder's contents (contents), Copy the link (link), Skip (skip)	Copy the folder's contents	What F5 and F6 to another drive or server do with a link to a folder (also a junction). Copy the contents: the folder it leads to arrives as a plain folder, and a move removes only the link. Copy the link: the link is made anew at the target, leading where it led. Skip: the link is passed over and counted as skipped. A move on the same drive always moves the link itself.
Undo a failed multi-rename	rename.undo_on_failure	On or off	On	A swap or a ring of names goes through temporary names. When a rename fails in the middle of one, on puts every name back at once; off stops there and the message names each file left under a temporary name, which Undo puts back.
Shift+F6 on several selected items opens a dialog	rename.selection_dialog	On or off	On	When on, Shift+F6 with two or more selected files and folders opens the rename dialog with the mask *.*, as Total Commander does, so a mask such as *.old renames them all. When off, Shift+F6 always renames the item under the cursor in the list.
F7 offers the name under the cursor	mkdir.prefill_cursor_name	On or off	On	When on, the new folder dialog starts with the name of the file or folder under the cursor, selected, so typing replaces it. When off, it starts empty.
One queue job per file or folder	queue.one_job_per_item	On or off	On	When on, copying, moving or deleting several files and folders puts each of them into the queue as a job of its own, in the order selected, so each can be paused, moved or cancelled on its own; an answer for all still holds for all of them. When off, the whole selection is one job.
Queue in a window of its own	queue.window_own	On or off	On	When on, Ctrl+Shift+Q opens the queue in a window of its own that you can move, resize and leave open while you work on in the main window; it shows each running job's file, progress, speed and time left. When off, the queue opens over the main window.
Jobs listed under the panels	queue.strip_rows	A whole number from 1 to 50	5	How many jobs the background bar under the panels lists, in the order of the queue window (Ctrl+Shift+Q), which shows them all.
Show jobs that run at once in the queue	queue.show_at_once	On or off	On	When on, the queue window (Ctrl+Shift+Q) also lists the copies, moves and deletes confirmed with OK, which run at once rather than wait in the queue: a group of their own at the top, marked "Runs at once", paused, resumed and cancelled like the other jobs. When off, the window lists only the jobs queued with F2 or into a list; the bar under the panels still shows every job.
Show the speed of all running jobs together	queue.total_speed	On or off	On	When on, the queue window shows under its list how many jobs run and their speed together once more than one runs, beside the selected job's line. When off, only the selected job's speed shows.
Leave out the lane column while all jobs share one lane	queue.hide_single_lane	On or off	On	The lane column of the queue window names what a job waits for: Local for the local drives, a server or share by its name, or Runs at once. When on, the column is left out while every job listed is in the same lane, so the paths get its room. When off, it always shows.
Packing, checksums, sync and multi-rename run at once	queue.tools_at_once	On or off	On	When on, packing, unpacking, creating and checking checksums, splitting and combining files, synchronizing folders and multi-rename start at once, even while a copy to the same drive is running, as copies confirmed with OK do; the queue window lists them as running at once. When off, they go into the queue and wait behind the jobs before them.
Look up FTP links when listing	ftp.resolve_links_in_listing	On or off	Off	On: an FTP folder's listing asks the server what each link points to (up to 64 links, one or two requests each) and shows them last. Off: links show at once and are looked up when you enter, open or copy one; a link to a folder then shows as one. For connections made after the change.
Ask before a password goes over plain FTP	ftp.ask_plaintext	On or off	On	On: before rCommander logs in to an FTP server without TLS, where the user name and password cross the network unencrypted, it asks you - for this time, or for the server until rCommander closes. Off: it logs in at once and warns afterwards. Anonymous logins send no password and are never asked about.
Upper and lower case on SFTP servers	sftp.case_sensitivity	One of Detect for each server (auto), Different names (Linux, Unix) (sensitive), One name (Windows, macOS) (insensitive)	Detect for each server	Whether an SFTP server takes Data and data for one name, as a server on Windows or macOS does. Detect: rCommander asks the server once when it connects, without writing anything. It decides whether copying a folder into itself under another case is refused and whether a rename that only changes the case goes through a temporary name. For connections made after the change.
Rights of a completed SFTP upload	sftp.upload_rights	One of Everyone may read (rw-r--r--, 644) (644), The group may write too (rw-rw-r--, 664) (664), Only you (rw-------, 600) (600)	Everyone may read (rw-r--r--, 644)	While an upload runs, its file on the server is readable by you alone. Once it is complete it gets these rights - unless the copy keeps the source's attributes, which come after. A file that is overwritten in place keeps its own. For connections made after the change.
Inventory sync every (minutes)	inventory.refresh_minutes	A whole number from 0 to 10080	60	How often each server inventory synced before is synced again; 0 syncs only when you ask (0-10080).

Plugins

Setting	Key	Values	Default	Description
Run plugins	plugins.enabled	On or off	On	Off: no plugin runs, and the built-in viewer shows every file. The plugins stay installed and keep their own switches. Protected.
Failures before a plugin is suspended	plugins.crash_limit	A whole number from 1 to 10	3	A plugin that crashes, hangs or runs out of memory this many times within five minutes is suspended until you resume it on this page (1-10). Protected.
Largest text a viewer plugin may write (MiB)	plugins.viewer_output_limit_mib	A whole number from 1 to 4096	256	A viewer plugin's text output stops at this size (1-4096 MiB); the viewer shows what came so far. Protected.
Show a viewer plugin's text in colour	plugins.viewer_token_colors	On or off	On	A viewer plugin can show a file as coloured text, as an editor does - keys, strings, numbers and comments each in their own colour. The colours are the theme's, in light and in dark; the plugin only says what each part is. Off: the same text without colour. The hex and binary views never show colour. Protected.
Extensions given to a plugin	plugins.associations	Pairs extension=plugin id, separated by spaces	empty	Pairs such as csv=<plugin id>, separated by spaces: that plugin shows the extension, ahead of what the plugins claim. Built-in formats come first. Empty: the plugins' own claims. Protected.
Development mode: accept unsigned plugins	plugins.development_mode	On or off	Off	For plugin authors: unsigned packages can be installed and run, marked as unsigned everywhere. Leave it off otherwise - a signature is what tells you who made a plugin. Protected.
Latest calls listed per plugin	plugins.recent_calls_shown	A whole number from 0 to 100	10	How many of a plugin's latest calls its details list, behind a click, and how many plugins_list answers with over MCP. 0 leaves the list out; the summary of the calls stays. Protected.
Largest file a compare plugin is handed (MiB)	plugins.compare_limit_mib	A whole number from 1 to 256	16	Two files are compared by structure (JSON, CSV) only up to this size each (1-256 MiB); larger ones are compared line by line, and the compare window says why. Protected.

A plugin's own settings are declared in its manifest and stored as plugin.<id>.<key>, protected like these; they are changed on the tab Installed with the plugin selected. The bundled viewers' settings are described in Plugins.

Import/Export

Setting	Key	Values	Default	Description
Export the settings	exchange.export.settings	On or off	On	Whether the next export starts with the settings ticked: every setting of this dialog, the protected ones too. The MCP token, the vault and the window positions are never exported.
Export the connections	exchange.export.connections	On or off	On	Whether the next export starts with the connections ticked: their folders, hosts, users, key paths and login scripts. Passwords and keys go with them only when you tick them in the export.
Export the trusted host keys and certificates	exchange.export.trust	On or off	On	Whether the next export starts with the SSH host keys and FTPS certificates you trusted ticked.
Export the hotlist and tabs	exchange.export.hotlist	On or off	On	Whether the next export starts with the directory hotlist and the folder tabs ticked. Places on a server or inside an archive are not exported.
Encrypt exports	exchange.export.encrypted	On or off	On	Whether the next export starts encrypted with an export password of its own. Each export keeps the choice it was made with. Protected.
Automatic backups to keep	backup.keep	A whole number from 1 to 1000	10	After each backup into the backup folder, the oldest backups with a generated name beyond this number are deleted. Backups you named yourself are never deleted. Protected.

Updates

Setting	Key	Values	Default	Description
Check for updates by itself	update.check_enabled	On or off	On	A check asks the release host for one public file per channel, with the user agent rCommander/<version> and nothing else: no cookie, no installation id, nothing about the system or its use. The host sees the address, the time and the version. Check now always works. Protected.
Hours between checks	update.check_interval_hours	A whole number from 1 to 168	24	The first check comes a few minutes after the start, then one every so many hours (1 to 168). Protected.
Channel	update.channel	One of Stable (stable), Beta (beta)	Stable	Stable offers releases only; beta offers pre-releases too and the release that follows them. Until you choose, the channel of the running version applies. Nothing older than the running version is ever offered. Protected.
Update source	update.source	An https:// folder serving the update manifests; empty for the official releases	empty	Empty for the official GitHub releases. A mirror is an https:// folder serving rcommander-update-stable.json, rcommander-update-beta.json and the packages below it; its manifests are checked against the key built into rCommander all the same. Protected.
Proxy for updates	update.proxy	Empty for the system's proxy, direct, or http(s)://host:port without a login	empty	Empty for the system's proxy (the Windows Internet options, HTTPS_PROXY and NO_PROXY), direct for none, or http://host:port. No user name or password: a proxy that asks for a login is not supported; copy the download address instead. Protected.
Show what is new after an update	update.whats_new_after_update	On or off	On	The first start after an update says so once; What's new opens the changelog. Protected.
Install updates by themselves	update.auto_install	One of Off (off), When quitting (on_quit), When idle (when_idle)	When quitting	Off: you install. When quitting (the default): a new version is downloaded in the background and installed as rCommander ends; the next start runs it, and a download not finished by then never holds up quitting. When idle: also restarts into it once nothing happened for the minutes below - no input, no job in the queue, no terminal or SSH session, no dialog. A version whose install failed is never installed by itself again. Protected.
Minutes without input before an idle update	update.idle_minutes	A whole number from 5 to 240	30	How long nothing may happen before "when idle" restarts into the update (5 to 240). Protected.
Days to keep the database copy after an update	update.backup_retention_days	A whole number from 0 to 3650	14	Before every update the database is copied; after a proven update only the newest copy stays, and after these days it goes too. 0 keeps it for good. Protected.
