FSO Copy Files / Folders

Set objFSO = Wscript.CreateObject("Scripting.FileSystemObject")
FileSystemObject.CopyFile source,destination,1

FileSystemObject.CopyFolder source,destination,1
ARGUMENTS

N.b
VBScript create object syntax:
Set objFSO = CreateObject("Scripting.FileSystemObject")
WSH create object syntax:

VBS & WSH do treat the above differently if parameters are used - see:
