I have recently migrated over my files from Windows to Mac OS and have noticed that my Music folder contains many AlbumArt_{*}.jpg files.
First of all I would like to know where these files are created. Secondly I actually tag many of my music files myself using a program called Tag&Rename and as far as I was aware these images are embedded directly into the MP3 files themselves. And lastly if I remove these will it effect anything in my iTunes library?
