This INIT/DA pair creates "soft partitions" of your hard drive, which
you can password-protect, encrypt, mount or unmount at will, and
resize (up to a maximum size set at initialization time).
Each soft partition is stored as an invisible file in the root
directory of the physical drive, with a filename like "MultiDisk
Partition #0000001234". The file will still work if made visible and
copied to the root of another volume, which has applications for
overcoming copy protection in certain programs that use a key disk to
bless a hard drive. You can create a soft partition just large enough
for the protected software, trick the key disk into authorizing it,
then pack the authorized partition into a StuffIt file and take it
anywhere.
Included here are versions 1.11 from 1989 and 1.29 from 1993. (The
about box for 1.29 misidentifies it as 1.28.)
