CDfs is a file system for Linux systems that `exports' all tracks and boot images on a CD as normal files. GPL

CDfs 2.6.23
These files can then be mounted (e.g. for ISO and boot images), copied, played (audio tracks), etc. The primary goal for developing this file system was to `unlock' information in old ISO sessions. The file system also allows you to access data on faulty multi session disks, e.g. disks with multiple single sessions instead of a multi session.
