I’m transferring for this instance MP4 format, COCO from Movies folder to New folder called Children folder, Cut and paste. Movie played fine in movies, but now when it’s in Children’s I have two copies neither play, unsupported format.
The purpose of this is to remove all cached metadata and xml data for an item that Plex usually keeps. This helps when you want to “start from scratch” for particular item
move all files for the media item out of the directory your Library is looking at so Plex does not “see” it anymore
