An iMovie library holds all the media and data used to make movies in iMovie. If your iMovie library is large and you want to free up storage space on your Mac, you can move your iMovie library to an external drive.
Before you move an iMovie library, it's a good idea to back up your Mac.
Moving your library to an external hard drive doesn't affect any iMovie Theater content you have moved to iCloud.

If you disconnect the external drive
When your external drive is connected to your Mac, the library you moved to the external drive opens automatically in iMovie. If you disconnect the external drive containing the library, iMovie opens to a new, empty library created in the Movies folder on your Mac. iMovie automatically saves any projects you create and media you import in the new library.

If you want to open the library you moved to an external drive, you can open it after you reconnect the external drive. You can then move clips, events, and projects between libraries.
