Cannot kill link to wrong movie file!

Plex Media Server Metadata & Adding Files
3

Try the Plex Dance.

This essentially makes it like the files were never in Plex, then you put back only the desired files.

  1. Move the movie and documentary out of the library, to a place where Plex cannot see the files (some place Plex doesn’t scan).
  2. scan the library (to detect changes)
  3. empty trash
  4. clean bundles
  5. double check naming schema and put back only the movie file, not the documentary.
  6. scan the library

If you want to keep the documentary, review Plex guidelines for Naming & Organizing Your Media. Specifically, the Local Files for Trailers and Extras document.
