Jellyfin doesn't seems to scan subfolders

[Duvel]

Regarding collections, it is not an issue to respect the folder structure and naming scheme at all because Jellyfin creates a "Collection" virtual library by itself

Example:



I have NOT done anything special with my folders to have this. Its precisely one of the job of the media center to organize and show things the right way, regardless of the storage folder structure, that should be all "flat" and respect standard naming scheme.

This is what you should do to deal with your collection of starwars and their "extras", which are clearly not extras here, but rather different versions of the same movie.

Movies
├── Star Wars (1977)
│  ├── Star Wars (1977) - [original].mkv
│  ├── Star Wars (1977) - [35mm].mkv
│  └── Star Wars (1977) - [ Despecialized ].mkv
└── The Empire Strikes Back (1980)
    ├── The Empire Strikes Back (1980) - 2160p.mp4
└── Return of the Jedi (1983)
    ├── Return of the Jedi (1983) - 1080p.mp4
└── The Phantom Menace (1999)
    ├── The Phantom Menace (1999) - 2160p.mp4
     

And so on.

If you want to keep them "together" in your folder structure, which I admit is easier to manage, you can also name their folders like this:

├── Star Wars (1977)
│  ├── Star Wars (1977) - [original].mkv
│  ├── Star Wars (1977) - [35mm].mkv
│  └── Star Wars (1977) - [ Despecialized ].mkv
└── Star Wars - Episode V - The Empire Strikes Back (1980)
    ├── The Empire Strikes Back (1980) - 2160p.mp4
└── Star Wars - Episode VI - Return of the Jedi (1983)
    ├── Return of the Jedi (1983) - 1080p.mp4
└── Star Wars - Episode I - The Phantom Menace (1999)
    ├── The Phantom Menace (1999) - 2160p.mp4

That should work (ie Jellyfin should properly identify them thanks to the year)

But for ultimate best results for jellyfin to parse the right movie, add either the tmdb or imdb ID in the folder name  (AND the file name too if you have multiple versions):

├── Star Wars (1977) [imdbid-tt0076759]
│  ├── Star Wars (1977) [imdbid-tt0076759] - [original].mkv
│  ├── Star Wars (1977) [imdbid-tt0076759] - [35mm].mkv
│  └── Star Wars (1977) [imdbid-tt0076759] - [ Despecialized ].mkv
