Plex Dance

Hello, Plex has an official discussion for this on the link here

The Plex Dance ™

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 will not “see” it anymore scan the library library (to detect changes) empty trash clean bundles (in menu next to server name, when accessed under ‘More’) double check naming schema and move files back scan the library Support articl…

It’s basically a bit of software to remove cached metadata from a file. Its seems to be buggy at the moment tho with lots of users reporting issues.
