Plex Documentation → Your Media → Naming & Organizing Your Movie Files
Follow Plex naming and organization guidelines. This will help Plex correctly identify the movies and not combine them. Adding the IMDB or TMDB ID to the folder and file name will also help.
Example: /Movies/Movie_Name (year) {imdb-xxxxx}/Movie_Name (year) {imdb-xxxxx}.ext
Plex Dance the movies, returning them to the system one at a time. This removes prior information from the Plex database, making it as if you are adding the movies for the first time.
