There are alot of .aac files on my Zune player. I’ve noticed that all of my .aac files are larger than my .mp3 files. Will converting them to .mp3 reduce the size of the audio file? If not, is there another way I can reduce the size of my .aac files on my Zune. The .aac files are taking up alot of space, and I don’t know why.

Thanks.
