Not finding collection of files

Both of these naming variants are wrong. So it is expected that Plex won’t recognize what you have there.

The required naming style for tv shows is this: https://support.plex.tv/articles/200220687-naming-series-season-based-tv-shows/

Here is a condensed writeup:

  1. Look up your show on TheTVDB
  2. Take the title as it is used on TheTVDB. If there is something in parentheses, take that too. If the title contains invalid characters (depends on your file system), like § : % *, simply leave them out.
  3. Check the naming and the folder structure of your show. Name the top folder of the show exactly after the title on TheTVDB. No abbreviations. No additional subfolders. No aliases. Add the (year) in parentheses of when episode 1 of season 1 of this show was aired.
  4. Name the episode files according to the above linked naming guide. Use the same title as for the top folder. Show's Title (year) - s01e01 - additional info.ext (‘- additional info’ can be left out)
  5. After you corrected the naming and folder structure, perform the Plex Dance with all files for this show.
