^^ a practice 99.99874592% of users frequenting this forum are currently employing. The (some) thousands of users with compliant file names and structures aren’t posting (frequently) because their stuff is working as expected.

I still think Plex should ‘Suggest’ in more forceful terms that a reading of the ‘Media Preparation’ section of the documentation will improve the Plex experience greatly, but I type fast and have those areas bookmarked as well as the Plex Dance Steps and by the time those are needed the user is generally more open to ‘Suggestions’.

TL;DR - Yea, we know.
