Stick to the naming conventions and you can reduce missing files and mismatches by almost 100%. And I recommend you to rename your files **before** adding them into Plex. Because Plex is storing a ‘bogohash’ of your media in its database. If it mis-matched an item because of a non-conforming file name, the bogohash is stuck in the database and Plex will continue to recognize this file as the wrong media – even after you rename it afterwards. This state can be only cleared with the [Plex Dance](https://forums.plex.tv/t/plex-incorrectly-identifying-tv-episodes/100265/4 "Plex Dance"). Which is bothersome and pretty annoying to do. Hence my recommendation: rename your files by default. The Plex naming schema is the most non-ambiguous of them all and is well understood by other media managers/player/servers. So there is no reason to not adhere to it. --- _[View the full topic](https://forums.plex.tv/t/10-episodes-not-showing-up/439086)._
