This naming scheme is made to be compatible with the [New Plex Agent](https://forums.plex.tv/t/new-plex-media-server-movie-scanner-and-agent-preview/593269/517) that now supports IMDb and TMDb IDs in filenames, if you don't need it or want it just remove `{imdb-{ImdbId}}`
** Please note that folder names are created (in the database) whenever the movie is added to Radarr, and it may be missing or incorrect at that time and your folder would have a blank ID!!!**
If you instead add it in the filename, the IMDb ID will be freshly pulled for any download or upgrade.
Another potential negative of using it in the folder is that folder renames are complex, lengthy, and potentially destructive in Radarr compared to file renames.
Keep in mind adding anything more after the release year could give issues during a fresh import in to Radarr, but it helps for movies that have the same release name and year.
TMDb is usually better as it guarantees a match, IMDb only gets matched if the TMDb entry has the correct IMDb ID association. We don't actually talk to IMDb.
