You're welcome.
I don't use FSO (WSH). I know it for the UT Forum. So, I never seeked more information about it. See more information about WSH in http://msdn.microsoft.com/library/default.asp?url=/library/en-us/script56/html/d78573b7-fc96-410b-8fd0-3e84bd7d470f.asp. And in Windows XP, go to Help and seek for WSH.
Good luck.
