Compact Disk File System

Windows 2000 provides support for the ISO 9660–compliant CDFS, which supports long file names as listed in the ISO 9660 Level 2 standards.

When creating a CD-ROM to be used on Windows 2000, you must adhere to the following standards:

  • All directory and file names must have fewer than 32 characters.

  • All directory and file names must be in capital letters.

  • The directory tree cannot exceed 8 levels from the root.

  • File name extensions are not mandatory.



CDFS adheres to ISO 9660 standards and therefore does not support lowercase file names. When you use CDFS to access a file or directory with a lowercase file name on a CD-ROM, you get a "File not found" error message.
