When I hook my phone up to my computer I cannot delete any of the music files I put on there. I wanted to move some of my music to the media file, but I don't have enough memory and they won't move, they will only copy. So I thought if I just delete them and re-add them then that would work, but they are not deleting. Everything else seems to be deleting fine. I tried everything I can think of, but nothing worked and I really don't want to reset my phone. Does anybody have any ideas on how to do this?
