CD-ROM filesystem

The CD-ROM filesystem provides transparent access to CD-ROM media, so you can treat CD-ROM filesystems as though they were POSIX filesystems. This transparency allows processes to operate on CD-ROM files without any special knowledge or work on their part.

The fs-cd.so manager implements the ISO 9660 standard as well as a number of extensions, including Rock Ridge (RRIP), Joliet (Microsoft), and multisession (Kodak Photo CD, enhanced audio).

We've deprecated fs-cd.so in favor of fs-udf.so , which now supports ISO-9660 filesystems in addition to UDF. For information about UDF, see Universal Disk Format (UDF) filesystem, later in this chapter.
