Very simple vb script to copy a file

Dim objFSOSet
objFSO = CreateObject ("Scripting.FileSystemObject")
objFSO.CopyFile "C:\test.txt", "D:\"

Also works for UNC paths:

Dim objFSOSet
objFSO = CreateObject ("Scripting.FileSystemObject")
objFSO.CopyFile "C:\test.txt", _ "\\AnotherPC\share$\Folder\test.txt"
