The documentation is consistent about how to name TV show files.
2014: It is important…
2022: …must be correct…
Both: ShowName - sXXeYY - Optional_Info.ext
Plex documentation, October 2014, via Internet Archive Wayback Machine:
Naming ‘Series’ & ‘Season’ Based TV Shows
It is important that both the folder structure and each episode filename be correct for shows to be correctly matched.
To name series/episode based shows:
- TV Shows/Show_Name/Season XX/ShowName - sXXeYY - Optional_Info.ext
Current Plex documentation: Naming and Organizing Your TV Show Files
Both the folder structure and each episode filename must be correct for the best matching experience.
To name season-based shows create files with the season and episode notation sXXeXX :
- /TV Shows/ShowName/Season 02/ShowName – s02e17 – Optional_Info.ext
The most important bit in the file name is the appropriate season and episode number notation s02e17 which in this example means Season 2 Episode 17
