I recently disconnected my hard drive from my media player to put on more files, to find that it had created a xlm and metathimb file for every video i had on my hard drive. Are these files necessary, and if not will the media player re-create them if I delete them?
The XML and Metathumb files are video metadata and coverart, respectively.
They’re created automatically if you have “Get Content Info” set to AUTO in the setup.
If you don’t care about metadata or cover art thumbnails, then turn off that feature and delete the files.
