>Wow... Thanks for the info, but that was a little too advanced. Any other ideas? Something with a smaller learning curve? :) Maybe even some kind of magical file breaker-upper program?

If you break up via another tool, the time to break up will be added and your disk punished for nothing ;-)
If Calvin's code is not your cup of tea, why not use
createobject( "Scripting.FileSystemObject"),
as the FSO methods are well documented and capable of working with large file sizes ?
