I’ve not been able to get this featurette to show up in Plex at all. I’ve tried placing the file in the same dir as the main film with the -featurette naming convention, with the subfolder naming convention, with the extras subfolder, without the extras subfolder. Nothing works. All my other extras for other films show up fine. This ONE file is the only one I am having problems with. Please help.
You have one folder level too much.
Omit the Tenet (2020) - Extras
folder.
You need to follow Plex naming requirements.
Plex Docs → Your Media → Movie Files (Naming and Organizing) → Local Files for Trailers & Extras
Example:
/Movies
../Tenet (2020)
..../Tenet (2020).mkv
..../Looking at the World in a New Way The Making of Tenet-featurette.mkv
Also, If you use the Featurettes
subfolder you do not need to add -featureette
to the file name.
Nope. I did ALL of that. None of it worked.
See my OP:
“I’ve tried placing the file in the same dir as the main film with the -featurette naming convention, with the subfolder naming conventions, with the extras subfolder, without the extras subfolder.”
For the record ALL of my other files are:
/Movie
/Movie - Extras
/Featurettes
/Deleted Scenes
etc… And they all work fine.
All three screenshots above are examples of things that DON’T work, even though they should.
/Movie - Extras
is not supported.
Re-scan the library if you rename/relocate files.
This works on my system:
/Movies
../Tenet (2020) [2160]
....Tenet (2020) [2160].mkv
....The Making of Tenet-featurette.mkv
..../Trailers
......Theatrical Trailer.mkv
Using a JellyFish test file in lieu of actual extras:

Literally this one file doesn’t work, no matter what naming convention I use, and I can’t figure out why.
I rescan my library after every change. Plex sees the file, it shows up for a second, and then disappears.
Please show all current contents of the Tenet (2020)
folder.
Please use “list” mode.
Please excuse my ignorance, I’m not sure what you mean by “list” mode
But here are the current contents of the folder:
/Movies:
. . . /Tenet (2020) 2160p:
. . . . . . Tenet (2020) 2160p.mkv
. . . . . . /Featurettes:
. . . . . . . . . Looking At The World In A New Way The Making of Tenet.mkv
I tried that exact naming convention and filing. It did not work. For some reason Plex just doesn’t want to recognize this ONE file.
Is there really a colon : at the end of the folder name? If so, lose it.
No there is not actually colon in the folder name, as it is a character that is literally impossible to use in a folder name. Windows will not allow it.
So yeah, sorry I’m not actually sure why I put the colon in
/Movies
. . . /Tenet (2020) 2160p
. . . . . . Tenet (2020) 2160p.mkv
. . . . . . /Featurettes
. . . . . . . . . Looking At The World In A New Way The Making of Tenet.mkv
I also tried
/Movies
. . . /Tenet (2020) 2160p
. . . . . . Tenet (2020) 2160p.mkv
. . . . . . The Making of Tenet-featurette.mkv
Do you have another version of Tenet in the same library?
Last resort: perform the Plex Dance with the whole “Tenet” folder.
