Well, comp.sys.mac is supposed to be obselete, but I don't think
any of the specific groups would fit this question, so I've redirected
followups to comp.sys.mac.misc (the new general group)

You are in luck-- Apple has such a thing available in their CD-ROM
software at apple.com-- it's called Foreign File Access (and it's
associated files, Audio CD Access, ISO 9660 Access, and High Sierra
Access). It's also available on the developer CD, and comes with Apple
CD-ROMs.  It makes the High Sierra disk look exactly like a mac disk except
that you can't tell how many files are on the disk.

High Sierra isn't MS-DOS at all.  It is entirely different, and MS-DOS
computers also need additional software to read it.
