My backup cmd file has been in use since XP, through Vista to Windows 7. It has worked on a new laptop in Windows 7 ever since Windows 7 was released. Recently it has stopped working getting an access denied, cannot create directory message. It is xcopying my own folders, not the default documents etc.
In a cmd prompt, xcopy d:\data z:\ fails with the error, but copy d:\data z:\ doesn't.
Has MS patched xcopy recently? If so, how can I get back the earlier version?
