XCOPY is a command used on IBM PC DOS, MS-DOS, IBM OS/2, Microsoft Windows, FreeDOS, ReactOS, and related operating systems for copying multiple files or entire directory trees from one directory to another and for copying files across a network.
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 /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"
XCOPY fails with an "insufficient memory" error when the path plus filename is longer than 254 characters and moving large files without the "/J" option (available only after Server 2008R2) can consume all available RAM on a system.
No open files
XCOPY will not copy open files. Any process may open files for exclusive read access by withholding the FILE_SHARE_READ
The Windows Volume Shadow Copy service is used for such situations, but
XCOPY does not use it. Therefore,
XCOPY is not useful for backing up live operating system volumes.
XCOPY deployment or xcopy installation is a software application's installation into a Microsoft Windows system simply by copying files. The name is derived from the
XCOPY command line facility provided by Microsoft operating systems.
In contrast, the installation of a typical Windows application will require a significant number of additional steps before the application is ready to be used. Most of this additional work involves, directly or indirectly, adding or modifying entries in the Windows Registry. Even when an application uses ordinary files for its own data, many common facilities provided by Windows require some type of registration step before they are available to programs. Usually, one or more specialized tools (such as Windows Installer, InnoSetup, or NSIS) are used to help coordinate these relatively complex operations.
