rGUI is an open source .NET front-end for Robocopy written in C#. It is designed for users already familiar with the Robocopy command-line switches and what they do, but who want the command parameters presented in a visual way.
It provides instant context-sensitive help taken right from the Robocopy documentation, and builds a full CLI command in real time as switches are selected, which can be copy/pasted to a DOS window to run, or executed directly from the application.
