Which operating system is `robocopy` included with?

Robocopy, which stands for "Robust File Copy," is a command-line tool that is included with Windows operating systems starting from Windows Vista and later versions. Its primary purpose is to facilitate reliable copying of files and directories while providing options for data backup.

In the case of Windows 10 and Windows 11, Robocopy is natively included and can be used directly from the command prompt, making it a powerful utility for managing file transfers and backups. The inclusion of Robocopy in these later versions builds on its functionality, providing users with enhancements and a more user-friendly experience for managing file systems compared to the older operating systems.

While earlier versions of Windows, such as Windows XP and Windows Server 2008, may have some command-line copying tools available, they lack the robust features found in Robocopy. Specifically, Windows XP does not include Robocopy by default, which leaves a gap in functionality compared to newer operating systems where this tool is tightly integrated.
