Robocopy (Robust File Copy for Windows) is a very strong tool, which integrated in Windows since Vista. But the tool has lots of parameters which makes it a bit difficult to use.
Yarcgui, which stands for "Yet Another RoboCopy Graphical User Interface", is a freeware tool to start the Robocopy in a graphical user interface with context helps and so on.
