RichCopy is a file copy utility program developed by Ken Tamaru of Microsoft Corporation, discontinued in 2010.
[1] 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,[2] although there are GUI interfaces for it.
Any process may open files for exclusive read access using the FILE_SHARE_READ attribute.
[5] Another company created the non-free program GS RichCopy 360, which can copy open files and has been developed further.
