About This Tool
The Cleanup Script for Windows is a small utility designed to keep your The Sims 4 user folder clean and healthy. It removes temporary cache folders and diagnostic log files that can build up over time and may cause lag, UI glitches, or confusing error reports — especially after game updates or frequent mod changes.
Important: Nothing is deleted automatically. Files are only removed when you manually run the script. This gives you full control and allows you to keep logs for troubleshooting if needed. The script checks whether it is running with Administrator rights. If not, it automatically restarts and asks for permission. This prevents situations where the script appears to “do nothing” because Windows blocks file access.
This script deletes the following data:
- onlinethumbnailcache (folder and all files)
- cachestr (folder and all files)
- ConfigOverride & Screenshots (folders – deleted only if empty)
- localthumbcache.package
- localsimtexturecache.package
- avatarcache.package
- UserData.lock
- notify.glob
- ConnectionStatus.txt
- GPU Benchmark / Score result files (
.txt) - lastCrash, lastException & lastUIException (all matching
.txtfiles) - BE-ExceptionReport & BE-UIExceptionReport (all matching
.htmlfiles) - WickedWhims & WhimsInfo logs (
.log/.txt) - Andirz_*.log (logs created by my own mods only)
No other files will be deleted. Your Saves, Mods, Tray files, and all personal game data remain untouched.
Why you should delete cache files?
Cache files are meant to be temporary. After patches, mod updates, or configuration changes, they can become outdated or corrupted. Deleting them forces the game to regenerate fresh data on the next start, which often resolves:
- random UI issues;
- long loading times;
- visual glitches;
- misleading error messages.
