# Does quitting apps free up disk space?

Mostly it frees memory, not disk space. A few things on disk do shrink after apps quit or the Mac restarts: swap files used under memory pressure, and temporary files some apps delete when they close.

That's why free space sometimes jumps after a restart. But caches, downloads and app data stay until you remove them, so quitting apps isn't a way to clean up storage. See [why System Data shrinks after a restart](https://storagestudio.us/faq/mac-storage-basics/why-does-system-data-shrink-after-a-restart).
