Hello!
I currently make use of the "Optimize Versions" feature of Plex. It places a "Plex Versions" folder in the same folder as the media like so:
/movies/Dune/Dune.mkv
/movies/Dune/Plex Versions/{{named version tag}}/Dune.mkv
I want channels to ignore these optimized versions as they're causing duplicate entries in my Channels library.
I would even be comfortable with an ignore file in the same vein as .gitignore and .plexignore where paths can be matched.
