This device has great sound, but...It doesn't support subdirectories. So all songshave to go into a single flat directory. Forme this is a major inconvenience. I liketo separate jazz, pops, classical, recordedbooks, etc.And, when you connect it to a computer,it doesn't appear as a normal directory, so you can'tuse it for data files.This is the sort of info that you can't determine fromthe product description. You have to buy it to find out.
