TV episode renaming does not support creating or renaming of folders.
It will only rename the episode file as per the selected format, or variation as per the renaming.
This section is very simple, and only the format of the season and episode is reversed to a regex in Media Companion.
At this time, I won't be adding creation of folders, or renaming of folders for TV section of Media Companion. It is on the roadmap, but when instigated, it will only be for the TV Series folder (renaming), and the season folder (creation and renaming).
Episodes in their own subfolder will not be created.
The extra path length will cause some problems, as I believe you have experiencing.
Is the need to have your episode in its own folder due to your media software? Also, on having the series title in the season 01 folder?
in your above example, the path length is already 166 characters.
Death in Paradise\ ...
is only 96 characters
Not trying to cause issues, but wishing to understand.
