After inserting a CD-ROM into the optical drive of my computer, two different accessible CDs show up on my desktop. One contains only audio files and the other some additional files. How is this possible? I thought that a CD cannot be divided into multiple partitions?
CDs store multiple tracks – an audio CD has a track for each song, while a data CD has a single track containing the entire filesystem. (Note that the audio tracks are not files even though some systems show them as such.)
