XCOPY

XCOPY is a shell command for copying files and directory trees from one directory to another or across networks. The command was designed to be more functional than the copy command, but to augment it instead of replacing it.

The name, short for extended copy, is often written as XCOPY or xcopy. As was the prevailing style for DOS systems, the name was typically written in all caps when DOS was a prevalent technology and even today in the context of such obsolete systems. In modern times and for modern systems, prevailing style is to write command names in lower case. Since the command's use spans from DOS to current systems, both representations are commonly used.
