# Does Storage Studio scan iCloud Drive for duplicates on its own?

Yes, if you leave it on. Each source in the **Duplicates** window — including **iCloud Drive** — has its own **Auto-scan** switch, on by default, so results are ready when you open the window. Scans of your Mac's own files wait until it's idle so they don't compete with your work.

You can also scan on demand with **Scan now** (it turns into **Stop** while it runs), and it only scans the source you're looking at.

Only iCloud files already downloaded to your Mac are compared; online-only files are skipped, so a scan never downloads anything. Results are remembered between launches.
