I am not surprised to find that most topics bearing "RoboCopy" bear my name.
The current AskWoody newsletter contains:-
The ability to mirror two folders has been a Windows feature for about 26 years, using the robocopy command at a command prompt.
Now, you can use robocopy with a graphical user interface (GUI), thanks to Martin Kinkelin’s open-source project, RoboMirror.
