CDFS

From Wikipedia, the free encyclopedia

This article is about the Linux virtual file system. For the name of the Windows file system device driver, 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 audio: Appears as a WAV file; reading from it will start CDDA ripping.
• White Book video: Appears as a playable MPEG-1 file containing audio and video streams.
• Yellow Book 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 image: Appears as a single bootable disk image file.

CDfs is not included in the mainline Linux kernel, but is instead distributed as a set of GPL-licensed patches against the 2.4 and 2.6-series kernels.

In Plan 9, 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.

On other Unices and operating systems such as Windows, cdfs may be the name of the ISO 9660 file system driver.
