All that you need are two files, Cardfile.exe and cardfile.hlp, both
exist in any copy of Windows 3.0 or 3.1 or Windows for Workgroups. It
runs just fine under 95/98/ME/XP, no "installation" is required, put the
EXE file in Program Files/Accessories, put the help file in
Windows/Help, and create a shortcut to the EXE file wherever you like.
It is frustrating not to be able to set the default directory for the
data card file.
