It was a music CD that someone created a CloneCD backup of. I downloaded this image from the net. It was RAR’d and it came with a .CDD file, a .SUB file, and a .IMG file (really big file).
I used CloneCD 4 to look at it, it shows all the tracks, but it only lets me make a music CD via a burner. I just want to see if there’s a way to extract the audio tracks from the image directly to MP3 files.
