If you searched "plex how to organize tv shows" because half your library is showing up as "Unmatched," duplicate seasons, or episodes in the wrong order, you are in the right place. I have been running a 14 TB Plex server since 2018, and in 2026 the rules are stricter than ever: the Plex TV Series agent has replaced the old TheTVDB agent by default, and tiny naming mistakes now cost you entire seasons. This guide walks through the exact folder tree Plex expects, the naming templates for every edge case (specials, multi-part episodes, date-based shows), the "Plex Dance" fix for stubborn mismatches, agent selection, and the batch workflow I actually use to clean up a messy library in one afternoon.
