Find undetected content

[FriendlyElk5019]

Is there a way to show content, that could not be identified by Jellyfin?

I'm not sure, but I feel like Jellyfin does not show all my movies and shows.

You can find UN-identified content in the metadata editor, IIRC.  Click on your icon in the top right and then "Metadata".  Movies and shows that are unidentified will NOT have the "movie" icon, like in my screenshots.

   
   

MIS-identified content is another story.  AFAIK, this has to be done manually.  Or you have to get creative with writing a script that queries the jellyfin database looking for metadata/folder path mismatches.
