Configuration

Settings reference

Settings persist as JSON in %LOCALAPPDATA%\SimpleZipDrive\settings.dat (edited via Settings in the app menu). A corrupted file is reported and replaced with defaults.

Setting	Type	Default	Meaning
MaxMemoryPerFileMb	int	512	Maximum RAM used to cache a single decompressed entry. Clamped automatically to 1 MB … 90 % of installed RAM; re-validated at every load
DefaultMountType	enum	DriveLetter	What the plain Mount menu item does: DriveLetter (auto M–Q) or Folder (asks for a folder)
AutoOpenMountedDrive	bool	false	Open the mount in a new Explorer window after a successful mount (explorer /root,"<mountPoint>")
CrossIntegrityMount	bool	false	(WinFsp only) Use permissive-DACL folder mounts visible to both standard and elevated processes; also forces folder mounting
CrossIntegrityMountFolder	string	""	(WinFsp only) Base folder for cross-integrity mounts; empty = %LOCALAPPDATA%\SimpleZipDrive\Mounts

Settings window

Settings in the menu exposes all of the above with validation (invalid RAM values show "Please enter a valid positive number for the RAM limit."). Open Config Path opens the settings folder directly.

Data locations

Everything lives under one root — %LOCALAPPDATA%\SimpleZipDrive:

Path	Purpose	Cleanup
settings.dat	Settings JSON	Manual (or delete to reset)
Temp\<pid>_<guid>\	Per-session disk cache + extraction workspace; name = process ID + random GUID	Deleted on unmount/exit; orphaned dirs swept at startup and via Clean Temp Files
Temp\Logs\debug_<timestamp>_<guid>.log	Current session log	Previous session logs deleted at startup
Temp\Logs\winfsp_debug_<timestamp>.log	Native WinFsp driver log, one per mount attempt	Kept until the next session's cleanup
Mounts\<ArchiveName>\	Cross-integrity mount-point folders (WinFsp)	Not auto-deleted; safe to remove when unmounted

The startup sweep only deletes Temp\<pid>_<guid>-shaped directories whose PID is dead and whose process name no longer matches (guards against PID reuse) — live sessions and settings.dat are never touched.

Resetting the app

1. Close all instances.
2. Delete %LOCALAPPDATA%\SimpleZipDrive (settings, caches, logs, mount folders all live there — nothing is stored in the program folder or the registry).
3. Start the app; it recreates defaults.

What is not configurable

• Drive-letter pool (M–Q) and the mount-point normalization rules (Mounting)
• Retry counts and backoffs (3 attempts / 500 ms steps for archive open; 2 retries for Dokan)
• Password attempt limit (3)
• Log retention (previous session's logs are removed at startup)
