For copying the single file, here is the code:
Function CopyFiles(FiletoCopy,DestinationFolder)
Dim fso
Dim Filepath,WarFileLocation
Set fso = CreateObject("Scripting.FileSystemObject")
If Right(DestinationFolder,1) <>"\"Then
DestinationFolder=DestinationFolder&"\"
End If
fso.CopyFile FiletoCopy,DestinationFolder,True
FiletoCopy = Split(FiletoCopy,"\")
End Function
