I can't get the new /W switch for the COPY command to work as described with the latest update ("VER /R" reports TCC 11.00.38 x64 Windows Vista [Version 6.0.6002]). Here are the steps I'm taking: I create two testing folders C:\A and C:\B. I copy some documents into A. I copy all the documents from A to B. I add a new document to B that isn't in A. I execute: COPY /W C:\A\*.* C:\B\*.* The command does not delete the file I added to B that isn't in A. Can you please advise me as to why this is failing? Thanks.
