SOLVED: No option to delete a file only from the library

[TheDreadPirate]

I created a test library with duplicates of a couple movies and created a test playlist.  I ensured that the volume in docker was R/W and that on the file system it had R/W permissions.  The user that the container runs as is the same UID as the bare metal Jellyfin instance.  100% has permissions to delete files if I so choose.

   
   
   

I checked the logs and there are no entries for any failures to delete files.

But this only applies to actual playlists. Not libraries. If you want to exclude items from your library, do what @theguymadmax said.

Or just not put it in the library folder.
