High Sierra Format

What Does High Sierra Format Mean?

High Sierra Format (HSF) is a file storage format used in early CD-ROMs. The HSF is now obsolete, but ISO 9660 is completely based on HSF for file storage and retrieval. Thus, High Sierra Format became a standard format for organizing data logically on compact discs.


Techopedia Explains High Sierra Format

Before the ISO 9660 standardization, every CD-ROM manufacturer had its own format for storing files on the disc. This led to confusion and incompatibilities. To avoid this, the most commonly used format, the High Sierra Format, was made a standard with slight modification. This standard enabled the manufacturers to follow one generalization for ease of designing as well as data storage for software and applications. High Sierra Format was made the standard in 1985 by the High Sierra Group. High Sierra Format is explicitly used very rarely, but now globally known to be the basis of the ISO 9660 standard.
