It's all in mp3 format. on my sansa I have I:/Music/Artists/Album/song.mp3
ahhhhh...I just plugged in my sansa to look at things.....something that is weird...I'm using Vista and the folders of music that appeared in RockAA or normal looking, the rest of the folders that RockAA didn't see immediately are somewhat transparent, like they are hidden... The properties for them were selected as hidden....weird.
I changed them to 'un-hidden' and all is golden....I wonder why some were hidden and others not....is that an artifact from when I used to sync my sansa with WMP11?
