Is there some reason why you are not using "cp" to accomplish your task?
"cp --help" should provide you with all sorts of options for copying files.
You should be able to press "cp" into service for this.

Using DOS utilities and DOS paths for this type of thing is putting you
on the fringes of support for Cygwin.  I really wouldn't recommend it.
Clearly this is not such a Windows-specific problem that it outside of
the capabilities of a UNIX solution.
