I know this is a late reply but I stopped naming my episodes with the “text name of the episode” in the file name at all, on all my TV Series for Plex - ON MY PC.
I stopped having problems with order and episode mix ups, unless there is an issue with a episode mix-up on the DVD you are ripping, itself, of course. (incorrectly named or numbered series episodes on your DVD or wrong on IMDB.com website in my case, etc.).
Meaning, instead of naming the file on my Plex server in this manner of the Walking Dead Series:
s06e13 - The.Same.Boat.mp4
I just renamed all the files like this:
s06e13.mp4 <–Just the Season, Episode and file type.
When Plex scrapes, the Plex engine names the episode as it appears on the IMDB website, and the episode name and description appear in Plex on my devices, correctly, pretty much every time.
I have stopped having any issues with “naming problems” since I started “keeping it simple” with the file names of my movies and TV series files in Plex,
–> ON MY PC, in the Plex Movie and TV Series Archives <-- I just want to make sure I am clear here, lol
When Plex parses the PC Plex Archives it pulls the names and series episode descriptions off the IMDB website, it is Plex which grabs the extra data, episode descriptions, pictures etc and adds all related series episode NAME and number with the description. perfectly in Plex without complicated names and descriptions,
Yes, while looking for a particular episode from your PC WITH File Explorer or whatever file management tool you use, you’ll only see the short name in the file listings as in The Walking Dead Series on my server I use:
s06e13,mp4
NOT,
s06e13 - The.Same.Boat.mp4
or
TWD.s06e13 - The Same Boat.mp4
or whatever “Plex file naming format” you decide to use.
Keep it as simple as possible: s06e13,mp4
I hope I explained myself correctly? I’m new to Plex and for the gurus, it is probably common knowledge. However for me. These are the techniques which have worked for me, better than the more detailed and complicated naming structures. All I am trying to say is let Plex do the TEXT naming of your files.
Keep your movie and series episode names as simple as possible:
s01e01.mp4 or s06e16.mp4 and Plex will add all the pertinent info in the browser automatically.
Movies are similar but I do add the Movie Titles in the file name as:
Justice_League.720p.mp4 (could use a . instead of a _ in every fie as well I believe?)
Please correct me if I am mistaken or totally incorrect however!
As I said, I am a relative newb using Plex, So please be gentle!
I just hope this helps someone else.
