Robocopy is hanging in the corner of your PC, maybe without you ever noticing it. It is a built-in command line for Windows operating systems that allows for quick file transfers from one place to another. On top of that, you can even transfer whole directories or drives.

This is not a commonly used command. It is actually an external command. Robocopy was available in the Windows NT and Windows 2000 resource kits and all the Windows operating systems after Vista (7, 8, and 10).

In this article, you will find all about the useful Robocopy commands and what they do.
