# Can Storage Studio free up space when my external drive isn't plugged in?

Partly. Anything that doesn't need somewhere to put things still works without the drive: clearing app caches, releasing space your Mac is holding in local backups, and making cloud files online-only.

Two kinds of help wait for the drive:

- **Moving folders or apps** needs the fast drive as the destination.
- **Clearing temporary or leftover folders** keeps a recoverable copy in the Recycle Vault, which lives on the fast drive. Without it the copy would sit on the same full disk and free nothing, so those rows are explained rather than offered.

Plug the drive in and the rest becomes available. See [Emergency Space without the drive](https://storagestudio.us/faq/freeing-space/emergency-space-without-an-external-drive).
