One movie not being found by plex scanners

There appears to be one movie that is in my movie directory that has not been successfully found/added to my library in Plex.

How can I figure out which film it is? I have close to 900 movies, so manually going one by one is not really practical.

I did some googling, but couldnt seem to find an answer that didnt involve a (now depreciated) plugin.

Any advice

Look for movie duplicates

Okay, that worked to significantly make the haystack smaller as I only had to go through the movies in which I had a 4k copy and 1080p copy for. For anyone googling https://support.plex.tv/articles/202393718-how-do-i-find-duplicate-or-merged-content/

I’ve identified the culprit. Split it to two separate entries, then fixed the incorrect match.

Thank you!
