Robocopy is already built into most recent versions of Windows (type robocopy /? at a command line), and will do what you want. (I believe the reason MS didn't add this functionality to xcopy is that it would break some scripts.)

Searching online resources suggests one must move all, overwriting existing files, wasting time in some situations. Must I fall back to XCOPY? Another alternative?
