# Does restarting my Mac free up space?

Sometimes, a little. Your Mac clears its temporary area when you restart, so anything apps left there goes away. The cache area isn't emptied by a restart — your Mac clears that by itself when the disk gets tight.

If a restart doesn't help, or space fills up again quickly, an app is likely leaving folders behind; Storage Studio measures both areas and names the app responsible.
