iCloud & iCloud Photos · Online-only files and Optimize Mac Storage
What do the cloud icons next to iCloud Drive files in Finder mean?
Short answer: A cloud icon in Finder means the file is online-only — stored in iCloud, not on your Mac. Opening it downloads it. A progress circle means it's syncing; no icon means it's downloaded and up to date.
A cloud icon means the file is online-only: it lives in iCloud and isn't stored on your Mac yet. Click it, or simply open the file, and macOS downloads it.
Other status marks you may see in Finder:
- A progress circle — the file is downloading or uploading.
- A dotted or waiting symbol — the file is waiting to upload.
- No icon — the file is downloaded and in sync.
Storage Studio's measurements follow the same rule: an online-only file takes no real space on your disk, so it never appears as a space hog in Storage Profile's Biggest space-users list, and it's skipped when scanning iCloud Drive for duplicates.
