Joliet Specification for CD-ROM

This article was previously published under Q125630
Content authors who are developing Windows 95 applications on CD-ROM shoulddevelop their titles according to the Joliet specification in order toincorporate Unicode file names and take full advantage of Windows 95 longfile name support.

The Joliet specification complies with the ISO 9660:1988 standard. It isdesigned to resolve some of its restrictions and ambiguities including:

  • Character Set limitations.
  • File Name Length limitations.
  • Directory Tree Depth limitations.
  • Directory Name Format limitations.
  • Unicode Character ambiguities.
Because the Joliet specification is ISO 9660 compliant, CD-ROM disksrecorded according to the Joliet specification may continue to interchangedata with non-Joliet systems. The designs for the System Use SharingProtocol, RockRidge extensions for POSIX semantics, CD-XA System Use AreaSemantics, and Apple's Finder Flags and Resource Forks all port in astraightforward manner to the Joliet specification. These protocols are notan integral part of the Joliet specification, however.

Support for Joliet is included in Windows 95, and the spec is now includedin the Win95 DDK docs. It will also be included in a future version ofWindows NT.
