Agnetha Falskog Cd's seem to be in this format.
cdfs will not play. wash factory oils off cd and they play. that's why I looked up cdfs. tried drivers, codecs and dvd players. but wiping it down made it work.
Was given a USB stick with pdf's on it . It was formatted CDFS. Can't delete or anything . Interesting! Behaves just like a cd.
