Media Sync also allows you to see your SD partition as well (so both at the same time). Makes it easy if you want to copy one to the other. I figure I'll use the internal slot since 1, I have backups of these things on my computer already (obviously) and 2, they're not going to change around much. Might as well have it out of the way and free up some card space.
BTW, Windows is such a little crybaby OS. I'm trying to copy my mp3 files to the internal memory and it gives me a warning "You may not be able to play this file"
Get over yourself windows. Sorry it's not a .wma
