Figuring out what wasnt scanned by Plex

I have a Drobo with around 5k movies on it. I can see that Plex missed about 250 movies. Is there an easy way to compare the 2 to determine which ones they are ? Comparing Windows Explore against Plex server just seems to painful to do, you would think there is a easier way.

Thanks

How to find the discrepancy between number of files on disk and the number of movies in the Plex movie library

Not just the number that I can see. Rather what the file names are that Plex didn’t recognize.
