# Is it safe to delete cache files on a Mac?

Mostly yes for app caches — by definition they're data an app can rebuild — but do it carefully:

- **Quit the app first**, so it isn't writing to its cache while you delete it.
- **Delete the contents of an app's cache folder**, not the Caches folder itself or random Library folders.
- **Expect a slower first launch** while the app rebuilds, and to sign in again in some apps.
- **Don't touch system folders** or caches belonging to macOS components.

Caches come back as you use apps, so clearing them is a short-term gain unless an app's cache has grown out of proportion.

Storage Studio clears only known rebuildable caches, shows what it will remove first, and keeps a recoverable copy in the Recycle Vault. See [freeing up space](https://storagestudio.us/faq/freeing-space/).
