File Search using WMI CIM_DataFile with VBScript

I looked around, but didn't find a script example that did exactly what I wanted, but I ran across several good alternatives. One thing I found was that if I don't specify the drive letter, it takes WAAAAAAAYYYYY longer to execute. Just a tip. In any case, I hope this helps someone out there...
