When importing large amounts of media from external sources, it can be tedious to double-check that each file was matched (forget about properly matched) in Plex. It would be nice to be able to run a report or have a filter that showed the paths of the files that didn’t get matched. Obviously some files we wouldn’t expect to get matched, but there are some that just need a slight naming tweak to be picked up.
There is a plug-in you can install that will do this, Plex-FindUnmatched
