In reply to Mike, I stand corrected. As to the *.CDA format, that's what I see when I look at the contents of an Audio CD. When I copy it to my hard drive it converts, I suppose you mean is extracted to the MP3 format. But how does the 44KB *.CDA file become a MP3 file of MB size? And does an audio CD actually have the MP3 file on it, or is it compressed, or what? HSF
