CDfs

For Compact Disc File System (CDFS), see ISO 9660.

CDfs is a virtual Linux file system that provides access to individual data and audio tracks on Compact Discs. A Compact Disc mounted with the "CDfs" driver appears as a collection of files, each representing a single track. It supports the following track types:

• Red Book CD-DA audio: Appears as a WAV file; reading from it will start DAE ripping.
• White Book VCD or SVCD video: Appears as a playable MPEG-1 file containing audio and video streams.
• Yellow Book CD-ROM data:
  • Apple HFS: Appears as a mountable HFS file system image (sans partition table).
  • ISO 9660: Each session appears as a mountable ISO image file.
  • El Torito boot File: Appears as a single bootable disk image file.

CDfs is not included in the mainline Linux kernel, but is instead distributed as GPL-licensed source package used to create driver modules for a Linux kernel from 2.4 or 2.6-series. It can also be embedded into custom Linux kernel source package to appear among mainline file systems.

In Plan 9 from Bell Labs, cdfs, is a 9P user-space server that operates similarly, presenting a Compact Disc as a directory of numbered files corresponding to disc tracks. Plan 9 cdfs, however, additionally allows disc recording.
