What is "richcopy"

RichCopy is a discontinued file copy utility program developed by Ken Tamaru of Microsoft Corporation. It is multi-threaded, and may thus under some circumstances copy files faster than some other utilities available for the Windows operating system. Additionally, while having some similarities (like multithreaded copying) with the Microsoft utility, Robocopy, it provides a complete graphical user interface (GUI), whereas Robocopy is a command-line utility.
