- PRODUCT :Windows NT

- The information in this article applies to:
-
- - Microsoft Windows NT operating system version 3.1

- Summary:
-
- Windows NT supports ISO 9660 CD-ROM format, but does not support any
- of the RockRidge CD-ROM format extensions. ISO 9660 is an
- international standard that defines a file system for compact discs.
- Almost all systems support ISO 9660.
-
- More Information:
-
- Level one ISO 9660 is similar to the MS-DOS file system. Filenames are
- limited to eight single-case characters, a period, and a
- three-character extension. Filenames cannot contain special or
- extended characters, (no hyphens, tildes, equal or plus signs), only
- single-case letters, numbers, and underscores. Directory names cannot
- contain three-digit extensions, just eight single-case characters.
-
- All alphabetic characters are in uppercase letters; some software maps
- these to lowercase letters. Either the filename or the extension may
- be empty, but not both ("F." and ".E" are both legal filenames).
-
- There is a "file version number" that can range from 1 to 32,767 and
- is separated from the extension by a semicolon. The file version
- number is ignored on many systems.
-
- Subdirectories are allowed to nest up to eight levels deep.
-
- Level two ISO 9660 allows longer filenames, up to 32 characters;
- however, most of the other restrictions still apply. Level two discs
- cannot be used on some systems, such as MS-DOS.
-
- The RockRidge extensions use some undefined fields in the ISO 9660
- standard to allow full UNIX-like filenames, symbolic links, and deep
- directories.
