## Copy file action - can't change name of destination file

I am trying to make a backup of a file I am going to overwrite. If I use
the Copy File(s) action it will not let me change the name in 'Destination
file name' after the change I go back into it and the file is renamed back
to the Source file name. Any way around this?

Example:
'Source file name' = C:\Program Files\Autodesk\Autodesk Design
Review\EComposite\ECompositeEditor.dll
to:
'Destination file name' = C:\Program Files\Autodesk\Autodesk Design
Review\EComposite\ECompositeEditor.old

At 10.1.1 on Windows Server 2003
