# What temporary files does Storage Studio measure and offer to clear?

Your Mac sets aside two areas that are, by its own definition, disposable: a **temporary area** it clears when you restart, and a **cache area** it empties by itself when the disk gets tight. Apps write to both knowing the contents can go at any moment.

Storage Studio measures both and attributes what's there to the app that put it there, so a large leftover stops being "space nobody can account for". It only offers to clear a folder after checking it on its own — see [how it decides a folder is safe](https://storagestudio.us/faq/freeing-space/how-does-storage-studio-decide-a-temp-folder-is-safe). Anything it clears goes to the Recycle Vault, so it's recoverable.
