Even if you don’t want to go the full route of creating a folder for each title (best practice for sure), even creating a few folders to break it out a bit can reduce some overhead. For example I have letter folders with batches of files in them. I’m currently working on getting that fixed up and the recommendations I got might be helpful if you go that route.
You may even want to give DBRepair a look as a more thorough DB cleanup option (Plex topic for it).
