Freeing up space · Caches and clutter
Can I undo a cache cleanup?
Short answer: No. Caches are rebuilt by the apps that own them, so they're cleared outright rather than kept. Other clear-ups go to the Recycle Vault, and moves can be reversed with Move back.
No — and there's no need to. Caches are data apps regenerate themselves, so Storage Studio clears them outright rather than keeping a copy. The app recreates whatever it needs next time it runs.
That's different from clear-ups of other folders, such as temporary folders an app left behind or duplicates: those go to the Recycle Vault so you can restore them. And moves to your fast drive are always reversible with Move back.
If you'd rather a cache was never cleared, untick it in the Free Up Space checklist.
