RichCopy

RichCopy is a file copy utility program developed by Ken Tamaru of Microsoft Corporation, discontinued in 2010. It is multi-threaded, which permits it under some circumstances to copy files faster than some other copiers available for the Windows operating system. It provides a complete graphical user interface (GUI), whereas Microsoft's multi-threaded Robocopy is a command-line utility, although there are GUI interfaces for it.

Features

 * Can copy several files simultaneously ("multi-threaded"), which under certain network conditions, may reduce the time required for file transfers.
 * Can be invoked either as a command-line utility or via a graphical user interface (GUI).
 * If used with the GUI, can generate the command line to carry out the action specified for the GUI.

Criticisms

 * Bugs not fixed before support was discontinued remain. RichCopy is best utilized by experienced users who know how to verify that copy operations have completed successfully without errors.
 * RichCopy is not supported by Microsoft. The program has not been updated since approximately June 2009, despite numerous users requesting bug fixes.
 * Duplicates Robocopy functionality.

Defects
RichCopy will not copy files that are opened with certain combinations of file sharing attributes. Any process may open files for exclusive read access using the FILE_SHARE_READ attribute. Another company created the non-free program GS RichCopy 360, which can copy open files and has been developed further.
