My mp3 player is the detachable usb that can plug into the comp.....I was loading music into it when my computer froze...now when i try to play my mp3 player the name just stays frozen on the screen but if i plug it back into the computer it reads....I tried deleting all the folders from the player but one of the folder gives a message saying it can't be deleted because the directory is not empty ...the music files in my player are corrupt from what I can tell so can anyone tell me how to delete corrupt files so I have a chance at saving my mp3...please
