EXE file
Ready to run on a PC (or on a
Datacomputer, if that is what the program is
designed for), but takes
more time to download than a ZIP file.
(Keep in mind that downloading an EXE file is
more prone to errors
than downloading a ZIP file. If an error occurs
when you download an EXE file, you may
unintentionally run a corrupted EXE file, while
if an error occurs when you download a ZIP file,
the UNZIP program will tell you that the file
has been corrupted.)
HHT file
Ready to be loaded into an HHT-500
handheld computer (using the SENDHHT.EXE program
or the OSIRIS.EXE Handheld menu),
ZIP file
Contains EXE, HHT, or other file(s),
but must be processed with
PKUNZIP or a compatible program before the program
is usable. (If you do not have an "UNZIP" program,
do not choose this option.)
