AppVault

Move an app's data to a backup drive.

A macOS app scatters its data across a dozen folders under ~/Library — Application Support, Containers, Caches, Preferences, Saved State, Logs, and more. AppVault finds every one of those locations for a given app, moves the data that actually exists onto a backup drive, and hands you the exact shell commands to reverse the move whenever you want it back.

What it does

• Finds all of it — derives every support-data path macOS may have created for an app, then keeps only the ones that exist on disk.
• Builds a backup plan — an ordered list of moves to a backup volume, shown for review before anything happens.
• Reversible — emits ready-to-run mv commands to restore every item exactly.
