Duplicates

The Duplicates window finds files that are exact copies of each other, by content rather than by name, and lets you keep one copy of each. Extra copies go to the Recycle Vault, so a removal can be undone.

For each set of duplicate files on your Mac, Storage Studio recommends keeping the copy you're most likely using — one in a working folder rather than Downloads or Desktop, then the most recently used — and you can always pick a different one.

The Duplicates window can find exact copies inside each connected cloud account by reading the fingerprints the provider already keeps, so nothing is downloaded. You can remove the extras there too, and every account is checked on its own.

With Auto-scan on, Storage Studio looks for duplicate files quietly in the background — on your Mac only when it's idle, plugged in and cool, and in cloud accounts during short pauses. It never removes anything on its own.
