Rock Ridge

Rock Ridge is an extension to the ISO 9660 volume format.

The extension adds support for storing Unix-specific file information on ISO 9660 CD-ROMs.

These extensions are, briefly:

• longer file names (up to 255 characters)
• almost any ASCII character can be used in file and folder names
• owner permissions can be stored
• symbolic links
• the long file names are argued to look better in Windows

See the ISO 9660 page about operating support for Rock Ridge.
