About the Default Devices
When you installed Final Cut Server, you entered a production media location. By default,
Final Cut Server creates three devices at that location: Library, Watchers, and Media.
The default Library, Watchers, and Media devices are actually just subfolders
Final Cut Server created in the production media location. Users can use these devices
as is; for example, they can add assets and productions to these devices.
