Freeing up space · Caches and clutter
What does the Clean App Caches button do?
Short answer: It clears only well-known regenerable cache subfolders inside apps' data — Cache, Code Cache, GPU caches, crash logs and similar — without moving anything. Your history, settings and personal data stay put.
It clears app caches only, right away, without moving any folders. Storage Studio removes the well-known regenerable cache subfolders inside apps' data — things like Cache, Code Cache, GPU caches and crash logs — and leaves everything else alone.
You'll find it in the menu bar popover's action buttons, next to Rollback Last Batch. It's the quick option when you want space back now and don't want any relocation; Free Up Space Now does the same cache clean plus moving rule-matched folders.
Apps such as chat and editor apps keep their history, settings and personal data. See clearing Claude, Cursor or VS Code caches.
