# Why can't Storage Studio quit the app that's using my folder?

Some apps aren't Storage Studio's to quit — for example something running as a system process or under another user account. In that case it says so plainly and asks you to quit it yourself, rather than trying to force it.

Other common reasons a polite quit doesn't finish:

- The app is showing an unsaved-changes dialog. Switch to it, save or discard, then press **Check again**.
- A Terminal window is sitting inside the folder. Change to another folder or close it.

Storage Studio confirms an app really exited rather than assuming it did, so **Check again** shows the true state.
