What does the command `robocopy` accomplish?

The command robocopy, short for "Robust File Copy," is specifically designed to copy files and directory trees efficiently, which makes it an ideal tool for backing up or migrating data. It has advantages over other copy commands, especially in terms of handling large amounts of data and providing additional features such as resume capability, the ability to mirror directories, and options for filtering files based on attributes.

Its robust nature means it can handle network interruptions, only copying files that have changed or are new, which can significantly reduce the time and bandwidth required during file transfers. It is built to maintain file permissions and attributes during the copying process, making it a powerful utility for system administrators and users who need reliable file transfer solutions.

Other commands mentioned, such as formatting a drive, initiating disk defragmentation, or verifying the integrity of system files, serve entirely different purposes and do not apply to the use of robocopy.
