In computing, XCOPY is a command used on PC DOS, MS-DOS, OS/2, Microsoft Windows, and related operating systems for copying multiple files or entire directory trees from one directory to another and for copying files across a network. XCOPY stands for extended copy, and was created as a more functional file copying utility than the copy command found in these operating systems. XCOPY first appeared in DOS 3.2.
Create a new directory by copying all contents of the existing directory, including any files or subdirectories having the "hidden" or "system" attributes and empty directories.
xcopy e:\existing e:\newcopy /s /e /i /h
If the directory names include blank signs(spaces), the names can be put in quotation marks.
xcopy "D:\Documents and Settings\MY.USERNAME\My Documents\*" "E:\MYBACKUP\My Documents\" /D/E/C/Y
Copy entire drive in to a mapped network drive while ignoring any errors in network restartable mode.
xcopy *.* z:\Netmirror /E /V /C /F /H /Y /Z 1>out.txt 2>err.txt
Copy a single file without prompt if it is a file or a directory
cmd /c echo F | xcopy "c:\directory 1\myfile" "c:\directory 2\myfile"
While still included in Windows Vista, Xcopy has been deprecated in favor of Robocopy, a more powerful copy tool, which is now built into the operating system. Windows 7
xcopy /? does not claim that it is deprecated.
Experience has shown (e.g., http://www.terminally-incoherent.com/blog/2007/02/05/xcopy-insufficient-memory/) that Xcopy fails with an "insufficient memory" error when the path plus filename is longer than 254 characters. Robocopy does not have this limitation.
