Hi, I found an mp3 player in my local park, and no one clamied it so it was given to me. Anyway, it plugs into my usb port and shows up as an external drive. I thought that it would be like most mp3 players, and I would just have to copy mp3s to the drive. The thing is, mp3's wont work on it. Observing the drive, the music files that were on it already were in mpy format. Is there any software that will allow me to make an mpy file out of my mp3s?
