 Kan, If I can make a suggestion, it is hard to find
a file splitter that was not intended to simply split
files so that they will fit on a floppy. A file
splitter designed to split really large files or even
volumes would be a great tool to have. I don't know if
you like the idea of including such a tool in the
XXCOPY program but it sure would be handy. Also it
would be super handy if it were designed to burn the
data to CDs and DVDs all from within XXCOPY. But then
again you might have had plans to have some sort of
personal life for the next few years or so.
