I am trying to ZIP up a folder in VBScript and it doesn\'t seem to work. I\'m certain I am creating the header file correctly.
It creates the actual file correctly,
you could call an external zip file via %comspec%
oShell.Run "%comspec% /c c:\windows\7za.exe a " & oFile &".zip " & oFile & " -tzip",,True
