In Manage Files, how to tell which ones are connected to content

Victoria.P.876

Hi there,
Please would you let me know if there is any way to distinguish files that are connected with content vs files that are not in manage files?

For context, the lesson has been ported over and brought a lot of files that seem to be mostly unrelated to the current subject though it is hard to know which ones are and are not "keepers".

Thanks for the help!
