      Next time try posting in the appropriate forum. You will find faster answers if you post your Java questions in Java instead of Misc.

          You'll need to provide more details on the windows utilities that you are trying to use.

              Have you tried some of the new i/O features in the java.nio packages? On the other hand, why do this task in Java at all?

                  You can execute MSDOS from java....

                  By using Process....

                  for executing MSDOS, i used "cmd.exe /C start cmd.exe"
                  for automatic transfer, i used("cmd.exe /C start "Something you could copy using DOS syntax/file transfer using COPY dos syntax");

                  if you know how to transfer files from a place to another, then you could just add that code to the Process...

                  if not,
                  Try to run DOS and inquire for help.....
                  There is a pattern there how to copy files from one location to another....
                  I guess it was "COPY" or something with a parameter/s....
