Using the Libraries panel
The Libraries panel gives you direct access to stock assets, graphics, Motion Graphics Templates, and LUTS created elsewhere and shared via Creative Cloud, inside Premiere Pro.
You can also place media files in your Creative Cloud Files folder, which will automatically populate Creative Cloud Files folders on other computers if you are logged in to your Creative Cloud account on those systems.
It’s straightforward to share folders with other users too, so the Creative Cloud Files folder is a useful way to share project files.
Premiere Pro works well with other file sharing services too. Only the file path (location) and filename matter to Premiere Pro for the purposes of linking clips and media, so provided your file-sharing service stores files locally or at an accessible network storage location, you should find Premiere Pro works as usual.
Network-based storage is sometimes too slow for media file playback, so check the sustained speed of your network before counting on it for video editing.
