Robocopy is a powerful command-line in Windows operating system that allows users to copy files, folders and partitions. It was first introduced in the Windows NT operating system as part of a resource kit in late 1993. It was continued in later versions such as Windows 2000, Vista, Windows 7, 8 and 10. Although it was not part of Windows XP and Windows Server 2003, users always had an option to independently download an official toolkit from the Microsoft Download Center.
