That blackberry folder has been on all my bb's since my pearl that is why I never had this issue. Cause all my stuff was already in there from when I set it up on my pearl. When you use a memory card from another device (non bb) is when you will see all your stuff out of that folder. Your BB will still see them and play them but not correctly all the time as this issue people are having is evident of.
