# Why did a clean-up free less space than Storage Studio predicted?

Because the result is measured on your disk, not taken from the plan — and Storage Studio tells you when the two differ rather than claiming success either way.

The common reasons:

- Your Mac may keep some of the freed space in its own local backups for a while; it usually comes back within about a day, or you can release it in [Local Snapshots](https://storagestudio.us/faq/freeing-space/what-is-the-local-snapshots-manager).
- An item was stopped, skipped because an app was using it, or only partly moved.
- New files were written elsewhere during the run.

If an item only partly moved, its row offers **Put the link back** to finish it — see [repairing a half-finished move](https://storagestudio.us/faq/freeing-space/what-is-put-the-link-back).
