Better Robocopy GUI

Description

It was designed for computer literates who like Robocopy but don't use it very often, and need to review legacy commands from time to time. This program is alternative to Microsoft's Robocopy GUI. Features: * Provide a property grid to present all optional parameters. * Provide a text editor to edit command line directly, and any change to the options in the text may be reflected back to the property grid, and vice-versa. * Provide immediate hints to an option highlighted in the property grid or in the text editor. * Test-run the robocopy command line without opening Windows' command prompt. * Some optional parameters of robocopy are exclusive or inclusive to each other, while some are just combination of others. The program may handle these scenarios properly.
