Managing libraries overview
Final Cut Pro allows you to work with multiple libraries. You can easily copy events and projects between libraries, which makes it simple and quick to move media, metadata, and creative work to another system so that you can edit on a portable computer, collaborate with other editors, or archive your projects and media. You can open and close libraries as needed so that you never have too many libraries open at once.
You can also manage storage locations for media files, cache files, and library database backups on a per-library basis. For more information, see Manage storage locations.
