Specification for
High Sierra/High Sierra Format
The Hotel in Nevada, USA where in 1985 the foundation was laid for determining the file systems for CDs. The efforts of the group which came to be known as the "High Sierra Group" led to the standard ISO 9660, the most common file system for CDs. A CD that conforms to this standard is at times still referred to as a "High Sierra" CD. The original High Sierra format has almost died out; as a rule, ISO 9660 is used instead.

ISO 9660
ISO 9660 describes the requirements a CD file system has to fulfill. This allows a CD to be used universally.
Only the capital letters from A to Z, the digits 0 to 9 and the underscore symbol are permitted for file and directory names. Diacritical marks (Ä, Ö, Ü), foreign characters and punctuation marks (ß, ?, ! etc.) as well as hyphens are not permitted. The filename can have a max. of 8 characters, the extension only up to 3. The filename must be at least one character in length, for example 'A'. A version number (1 to 32767) can be appended (for example 'A.B;1'). A maximum directory hierarchy of eight levels is permitted whereby the root is considered the first level. The ISO 9660 employs specifications of the High Sierra Group and is for that reason also called the High Sierra format. There are also other file systems ( for example, Joliet for Win95 or HFS for Apple Macintosh) which, however, can only be recognized on these types of systems.
Joliet
CD file system that supports long filenames and can be used under Windows
95.For full compatibility to DOS, an ISO 9660 file system must be created. This is a part of the complete Joliet system.
