I'm also not too sure what else this VB does. It's very small (36kb). The
old folder (D Drive) is actually a CD Rom on the new machine. I do know what
the folder name and the fiile is that the program is looking for. So I
could burn a CD with the appropriate folder tree on it, load it to the CDR
and see what happens when I run the program. But not sure what else the
program does. I don't want to miss anything.
