Notepad3 Settings (Notepad3.ini)


This section can be used to redirect to a settings file which should be used by Notepad3.
If a non elevated user is not allowed to write to the program directory of Notepad3.exe,
the side-by-side Notepad3.ini can point to a place, where the user is allowed to write his settings,
for example :


or a to have user specific settings:



This settings are read and written by Notepad3’s user interface.
For examples all Menu ? Settings will go here.




This section offers some advanced Notepad3 program settings, and can only be edited manually.
Press Ctrl+F7 to open the Notepad3 ini-file. Most changes only take effect upon restarting Notepad3.

  • (-> (Locale dependent short format)


  • (-> (Locale dependent long format)

Specify the short/long date and time formats. This is the format parameter passed to
the strftime() function.
Note that the locale will be set to English (because of the English Visual C++ Run-time
Library used by Notepad3).


  • (-> $Date:[^\$]+$) (Find-Pattern to Update Stamps)


  • (-> \$Date:[^\\$]+\$ | $Date: %Y/%m/%d %H:%M:%S $
  • (-> $Date: %s $) (Print format should fit to TimeStampRegEx)

This parameter is used as a regex pattern to match time-stamps which will be updated to
current date-time by Shift+F5, e.g. $Date: 2018/04/26 00:52:39 $

  • Default DateTime formats are:
    1. SHORT: [Settings2] DateTimeFormat= (empty) - Notepad3's language locale short ' ' format is used
    2. LONG: [Settings2] DateTimeLongFormat= (empty) - Notepad3's language locale long ' ' format is used
    3. TIME_STAMP: [Settings2] TimeStampFormat= (empty) - "$Date: %s $" where '%s' is replaced by time/date in
      DateTimeFormat. E.g. [Settings2] TimeStampFormat=#TimeStamp=2020-07-21 16:02:23 #
  • All DateTime formats accept the strftime() format string.
    Addon: TimeStampFormat accepts '%s' (which is no valid strftime() formatting code) - a placeholder for a DateTimeFormat formatted current date/time string. (mixing of strftime() and '%s' is not allowed).
  • If you define your own TimeStampFormat, you should define the corresponding TimeStampRegEx regular expression pattern accordingly (for our example: [Settings2] TimeStampRegEx="#TimeStamp=[^#]+#"), so that Update Timestamps operation can find and update them correctly.
  • Additional Menu Point: Insert Current Timestamp.


Specify the default directory for the open and save dialogs, used if no file is opened.

  • Path-names can be relative to the Notepad3 program directory.


  • Specify the default extension for saved files (omit the leading dot, just like txt or html).


This items are managed by Notepad3. (Menu->View->Position->Save as Default Position)
(Will set current window position as "Default Position" - can be recalled by Ctrl+Shift+P Hotkey)



Specify the path of an external program that is launched when pressing the Browse toolbar button.
Defaults to minipath.exe, which is the file browser plugin.

You can specify additional command line switches, and the file currently opened in Notepad3 will be appended as the last command line parameter.

Note: Due to special treatment of quotes by the Win32 ini-file APIs, pathnames with spaces need to be quadruple-quoted (""path to/file.exe""), but only double-quoted if there's additional command line arguments ("path to/file.exe" /arg).

On the other hand, our preferred file browser is minipath.exe (Menu->File->Browse... Ctrl+M) + Toolbar-Button.

If you don't like it, you can configure e.g.


We have integrated of a Powerful External Tool called grepWinNP3.
grepWinNP3 is a simple search and replace tool which can use regular expressions to do its job.

This allows to do much more powerful searches and replaces in Files.

grepWinNP3 can be launched:

  • from "File --> Launch --> Search in Files"
  • or from "Edit --> Search --> Search in Files"
  • or simply with "Ctrl+Shift+F"


The interval (in milliseconds) to check for external modification of the currently opened file.

  • Defaults is 0 ms.




Specify filters for the open and save dialogs

  • (Example: Text Files|*.txt;*.wtx;*.log;*.asc;*.doc;*.diz;*.nfo|All Files|*.*).


The size limit, in megabytes, to display a warning message for large files.

  • A value of 0 disables the warning.


Control if Notepad2 should allow multiple files on the command line (set to 1).
The default behavior is to accept only a single file, without quoted spaces, like Windows Notepad (set to 0).
The command line switches + and - can be used to override this setting on the fly, and the /z command-line switch has the same effect as the - switch.


Set to 1 to disable simple language detection for cgi and fcgi files.


NoCopyLineOnEmptySelection=1 to avoid the copy line (Ctrl+C) on empty selection.


NoCutLineOnEmptySelection=1 to avoid the cut line (Ctrl+X) on empty selection.


Set to 1 to disable fading of hidden objects in file lists (such as Favorites, etc.).


Set to 1 to disable file variable parsing.
Encoding tag parsing can be disabled in the Menu ? File ? Encoding ? Default dialog box.

Notepad3 can parse a few of the Emacs variables that can be used in source code files.
The first 512 bytes of a file (and, if nothing is found, also the last 512 bytes) are checked for the following constructs (can be manually disabled in the ini-file, or the File, Encoding, Default dialog box, respectively):

coding: utf-8;
mode: python;
tab-width: 8;
c-basic-indent: 2;
indent-tabs-mode:  nil;
c-tab-always-indent: true;
fill-column: 64;
truncate-lines: false;
enable-local-variables: true;

coding: Serves as a file encoding tag. Details about using encoding tags are outlined in the
Notepad2 Encoding Tutorial.
mode: Indicates the syntax scheme to be used, and is either the name of a scheme, or a
file name extension.
c-basic-indent: Denote tab and indentation settings.
indent-tabs-mode: Determines whether to insert tabs as spaces (nil, false or 0)
or not (true or 1).
c-tab-always-indent: Configures whether the tab key re-formats indenting white-space
(true or 1) or not (nil, false or 0).
fill-column: Sets the desired limit for long lines (but does not automatically display
the visual marker).
truncate-lines: Controls word wrap (enable: nil, false or 0; disable: true or 1).
enable-local-variables: Disables file variable parsing (nil, false or 0), but keeps
evaluating encoding tags.

To bypass both file variable and encoding tag parsing, reload the file with Alt+F8.
Adapt the settings mentioned above to permanently turn off file variables and encoding tags.


Set to 1 to disable simple HTML/XML detection for files without extensions.


If set to 1, recent files and other path settings referring to the My Documents directory tree are stored relative to My Documents.
This enhances USB stick portability between different versions of Windows, which are using different locations for My Documents.
This setting has no effect if Notepad3.exe itself is located inside My Documents (or a sub-directory thereof).

  • The default is 1 (enabled) if RelativeFileMRU is enabled, and 0 (disabled) otherwise.


Opacity level (in %) of the Notepad3 window in transparent mode.


Opacity level (in %) of the Find/Replace window in transparent mode.


Set to 0 to disable recent files on the same drive or network share as Notepad3.exe being saved with relative path-names.

  • The default is 1 (enabled).


This items are managed by Notepad3. (Menu->Settings->Window->Reuse Window Ctrl+Shift+L)

  • If set, another started Notepad3 instance will try to give control to the currently opened Window and quit.



Set to 1 to prevent indentation guides from jumping across empty lines.


This items are managed by Notepad3.



Application User Model IDs (AppUserModelIDs) are used extensively by the taskbar in Windows 7 and later systems to associate processes, files, and windows with a particular application.
In some cases, it is sufficient to rely on the internal AppUserModelID assigned to a process by the system.
However, an application that owns multiple processes or an application that is running in a host process might need to explicitly identify itself so that it can group its otherwise disparate windows under a single taskbar button and control the contents of that application's Jump List.

Most recently used (MRU) source lists are resident on the user's computer and contain information about source paths used in previous installations.
This information can be used when prompting the user for a source path.
Control system MRU, task-bar and jump list behavior.
See Replacing Windows Notepad for detailed explanations.


This items are managed by Notepad3.

  • Menu->View->Position->Sticky Window Position (Will remember current window position on restart, instead of last closed position (save on exit))




UseOldStyleBraceMatching=1 to switch back to (not recommended) old style behavior


WebTmpl1MenuName=Open Web Action 1


`WebTmpl2MenuName=Open Web Action 2


Put in here all ASCII chars which should be word delimiter in case of "Accelerated Word Navigation".


Is set automatically for CJK input languages (GetACP()).

If you define your own character-set in AutoCompleteWordCharSet, Auto-Completion word list is limited to words composed of these chars only (case insensitive).)


New configuration .ini-file: [Settings2] AutoCompleteFillUpChars=
To get the "Enter" completion behavior back, define: [Settings2] AutoCompleteFillUpChars=\r\n
I you like to allow more "fill-up" characters (accept completion item), just add them:

  • e.g. [Settings2] AutoCompleteFillUpChars=\r\n[(. (will accept completion item & adds the char).


It will be appended/removed to the comment tag on line comment block toggle.
If the string contains spaces, you have to double-quote it,

  • e.g. [Settings2] LineCommentPostfixStrg=" " to add a space after the comment tag (origin and title of this feature request).






This parameter is not used at the moment.


Encoding Detector information in Titlebar. This parameter is used to "debug" UCHARDET


Confidence/Reliability level for reliability switch in encoding dialog.


Bias/Bonus on top of Confidence/Reliability if current system's ANSI Code-Page is file encoding analysis result.
(This will push detection algorithm to like system's ANSI Code-Page more than other detection result)


The # (hash) is the start of a line comment in MySQL dialect.
But if this is confusing, it can be switched off by providing an option to Scintilla's SQL-Lexer
(set option: lexer.sql.numbersign.comment to 0 (zero)).

Unfortunately, in Notepad3, this can not be done by configuration, it can only be done hard coded.

  • Ed.: The default is "OFF", it is set to "ON" explicitly in Notepad3 (hard coded) to preserve old behavior,


The leveling of ESC behavior (msg-boxes -> selection -> exit) leads to following implementation:

New parameter "[Settings2] ExitOnESCSkipLevel = 2"

  • Level 2 : ESC cancels every single state separately (the default).
  • Level 1 : ESC cancels message-box and ignores Selection.
  • Level 0 : ESC cancels all states and proceeds to Exit (if configured).


  • A value of zero (0) (or less than 100 ms) will disable the Tooltip display.


  • Screen/Display Scale Percent threshold to switch to bigger file types icons (lexer style selections)





  • If not defined or empty the default behavior on Ctrl+Click URL is done:
  • The URL-String is send to OS via ShellExecute(), which will try open the URL using the registered protocol (e.g. http:// or file://) - in most cases the default browser resp. the file, if extension is known.
  • If defined, e.g. "D:\PortableApps\GoogleChromePortable\GoogleChromePortable.exe", this application will be started on Ctrl+Click.


  • (use ${URL} as place holder for clicked Hyperlink URL string)
  • Defining the argument/parameter string for the above application (only taken into account if HyperlinkShellExURLWithApp is defined).
  • If not defined, empty or set to "${URL}", the argument for the app will be the URL-String clicked.
    You can specify more command line parameter for the app here. The token ${URL} within the string will be replaced by the URL-String clicked. E.g. HyperlinkShellExURLCmdLnArgs="--incognito "${URL}"" will start the Chrome-Browser (see HyperlinkShellExURLWithApp) in "incognito mode" trying to open the clicked URL.


  • ShellExecuteEx()::lpVerb (""=default, "edit", "explore", "find", "open", "print", "properties", "runas")

[Statusbar Settings]

This section provides the ability to set the number, order and width of columns,
and the prefix text of the status bar fields.

VisibleSections=0 1 12 14 2 4 5 6 7 8 9 10 11 (internal default)

This parameter is used to define, which fields of the Status Bar should be visible.
If used, this setting also defines the field ordering.

  • Section 0 = Ln : Line number of Caret position / Number total of lines in the file
  • Section 1 = Col : Column number of Caret position / Limit for Long Line settings
  • Section 2 = Sel : Number of characters selected
  • Section 3 = Sb : Number of bytes (Bytes in [UTF-8]) selected
  • Section 4 = SLn : Number of selected lines
  • Section 5 = Occ : Number of Marked Occurrences
  • Section 6 = Size of file in [UTF-8] Mode
  • Section 7 = Encoding Mode (double click to open Encoding F9 )
  • Section 8 = EOL Mode (Toggle CR+LF, LF, CR)
  • Section 9 = Toggle INS/OVR Mode
  • Section 10 = Toggle STD/2ND Text Mode (Default Text or 2nd Default Text)
  • Section 11 = Current Scheme (double click to open Select Scheme )
  • Section 12 = Character Count (per line)
  • Section 13 = Replaced Occurrences
  • Section 14 = TinyExpr Evaluation

SectionPrefixes=Ln ,Col ,Sel ,Sb ,SLn ,Occ ,,,,,,,Ch ,Repl ,Eval , (internal default)

This parameter is used to redefines the displayed Prefixes in the sections of the Status Bar

  • A “,” (comma) is used as separator. Spaces are NOT ignored.

SectionPostfixes=,,,,,,,,,,,,,,, (internal default)

This parameter is used to redefines the displayed Postfixes in the sections of the Status Bar

  • A “,” (comma) is used as separator. Spaces are NOT ignored.

SectionWidthSpecs=30 20 20 20 20 20 0 0 0 0 0 0 20 20 20 (internal default)

This parameter is used to define the relative width of each field of the Status Bar

  • 0 = space optimized fit to text (dynamically adapted to width changes)
  • -n (neg. val) = fixed width of section [pix] , longer text is truncated

Fine tuning: increase, decrease or modify the value of numbers,

  • e.g.: ;;;;;;;;;;;;;;;;; 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14
  • SectionWidthSpecs=50 40 42 40 36 40 0 0 0 0 0 -10 40 40 -40


This parameter is used to define start counting of column (Col) at 0 or 1.

The merit goes back to @RaiKoHoff for the collection and documentation of Notepad2 / Notepad2-mod settings and the creation of a lot new parameters in Notepad3.ini. 👍 ❤️

@everyone: Your questions and remarks are welcome.

Also feel free to add more documentation, comments, corrections, etc...

@hpwamr : nice piece of work 👍 😄
It rises (again) the question: Where should the documentation of Notepad3 be bundled?
Meanwhile we have several places:

We are missing a clear and straight concept here (and a voluntary to take this challenge 😉).

Hello @RaiKoHoff, I understand your preoccupation.
My preference goes to number 1:
Well, I'm going to ask "Derick Payne" @rizonesoft for a clear vision of the future of his Notepad3 ! 🤔

@rizonesoft rizonesoft commented Aug 21, 2018

@hpwamr I am working on a solution to easily keeping the documentation up-to-date with little effort. @RaiKoHoff Thank you brother for all the hard work. I will keep you guys updated.

I add PreferredLanguageLocaleName=zh-CN within [Settings2] section in Notepad3.ini, however, the languange of UI doesn't become Chinese. What should I do?

The version of Notepad3 I am using is v4.18.512.992.

@hpwamr hpwamr commented Sep 16, 2018

@byuansh , the version v4.18.512.992 is not localized.

  • Localized versions are still in beta development and are not yet published publicly. 😉
    Please test: beta_v4.18.914.1104 or higher and in its "Notepad3.ini", section [Settings2] change the setting: en-US to zh-CN.
    The latest beta can be found here: Notepad3 Development

Could a link to this ini-file documentation be placed in a comment at the top of the "pristine" ini-file distributed with the app? This way users poking around in there could easily find it.
