SUMMARY
=======

When you view disk information for a CD-ROM in File Manager, free disk space is
always reported as zero (0) bytes, and total disk space in use is always
reported as approximately 127 megabytes.

Microsoft Mulitmedia CD-ROM Extensions (MSCDEX.EXE) is coded to report a specific
number for both free space and bytes in use. Microsoft has confirmed this to be
a limitation of MSCDEX.EXE (all versions).

Microsoft Windows NT uses a different file system for addressing CD-ROM drives
and does not have this limitation.
