Hello. I transferred a rather large mp3 to a 2 gig card. I went to put another one on there. By my calculations it should have fit. When I looked there were 3 copies of the first one that I transferred. They were bp_doc.mp3 bp_doc.txt._DD bp_doc.txt._IX What do these mean? How can i get it to just transfer the mp3 or can I? I couldn't find any information about it on the manual. Thanks for help in advance. Sharon
