Files keeps selected older states of a file when its contents change.
- Select the file and open Details.
- Open the Versions tab.
- Select the restore control beside the version you want, or select its timestamp to download that version.
Restoring makes the selected version the current file. Versions are not created for every individual keystroke: changes close together are consolidated, and older unnamed versions are thinned automatically over time and when version storage needs space. A named version is protected from automatic expiration.
Older file versions are managed separately from the active-file-plus-trash usage shown against your Vault quota. The Automatically remove deleted files after 30 days switch applies to Deleted files, not version history, and does not change the version-retention behavior described above.
Version history helps recover an earlier state of one file. Keep an independent backup of important data.
