# How do I move my Photos library to an external drive and keep iCloud Photos working?

Use Photos' own method: copy the library in Finder, open it in Photos, then make it the System Photo Library.

1. Quit Photos.
2. In Finder, drag **Photos Library** (in your Pictures folder) to the external drive. Use a drive formatted as APFS, and not one you use for Time Machine.
3. Hold **Option** while opening Photos and choose the library on the external drive.
4. In **Photos → Settings → General**, click **Use as System Photo Library** so iCloud Photos uses it.
5. Once you've checked everything is there, you can delete the old library from Pictures to free the space.

Keep the drive connected whenever you open Photos. Storage Studio doesn't do this for you because Photos needs to make the switch itself — see [why](https://storagestudio.us/faq/icloud/can-storage-studio-move-my-photos-library).
