Not even if you attempt to use MusicBee to sync a music device?I've been using MB since 2009, and sync to many different devices. I have never seen anything like that.
What version of MB are you using? And where did you download it from?
Good to know, thank you. It is possible that it's another program doing it since I can't determine what program is doing it, but it does seem to only be happening to my music files.
It's version 3.1.6585 and I believe I downloaded it from the official site - I downloaded it some months ago and don't remember exactly.
