Is it better to move files off my Mac or delete them?
Short answer: Move anything you might want again and delete only what's disposable, such as caches apps rebuild. Storage Studio clears rebuildable data recoverably and moves your own folders with a link left behind.
If you might want something again, move it; if it's genuinely disposable, delete it. Rebuildable things — app caches, old temporary files, downloads you've already installed — are fine to clear. Your own work, photos, projects and big libraries are better moved, because deleting them is permanent once the Trash is emptied.
Storage Studio is built around that split:
- caches and leftovers apps rebuild are cleared, with the removed copy kept in the Recycle Vault for a while;
- your own folders and apps are moved to the external drive with a link left in place, and can be moved back.
The one thing moving costs you is availability: moved files are there while the drive is plugged in. See Freeing up space.
