Ergotech ET-UC88

Question

This a different model than the 1021 but I'm hoping you can help me anyway. I have the UC88 and all of the manuals supporting CD manual etc asre in Chinese!! I have very basic needs for my MP3 ... All I want to do is load my music, play on random or have the option to play by folder / artist.I have figured out how to do everything except how to play all the tracks in the various folders randomly / shuffle.Can you help?
