Copy files and/or directory trees to another folder. XCOPY is similar to the COPY command except that it has additional switches to specify both the source and destination in detail.

XCOPY is particularly useful when copying files from CDROM to a hard drive, as it will automatically remove the read-only attribute.

Syntax
XCOPY source [destination] [options]
Key
source : Pathname for the file(s) to be copied.

destination : Pathname for the new file(s). [options] can be any combination of the following: Source Options
/A Copy files with the archive attribute set (default=Y)
/M Copy files with the archive attribute set and turn off the archive attribute, use this option when making regular Backups (default=Y) /H Copy hidden and system files and folders (default=N)
/D:mm-dd-yyyy Copy files that have changed since mm-dd-yyyy.
If no date is given, the default is to copy files with a modification date before today.
(at least 1 day before)
/U Copy only files that already exist in destination.
/S Copy folders and subfolders
/E Copy folders and subfolders, including Empty folders. May be used to modify /T.

/EXCLUDE:file1[+file2][+file3]...

(Windows 2000 only) The files can each contain one
or more full or partial pathnames to be excluded.
When any of these match any part of the absolute path
of a SOURCE file, then that file will be excluded.
For example, specifying a string like \obj\ or .obj will exclude
all files underneath the directory obj or all files with the
.obj extension respectively. Copy Options
/W Prompt you to press a key before starting to copy. /P Prompt before creating each file.

/Y (Windows 2000 only) Suppress prompt to confirm overwriting a file.
may be preset in the COPYCMD env variable.
/-Y (Windows 2000 only) Prompt to confirm overwriting a file. /V Verify that the new files were written correctly.
/C Continue copying even if an error occurs.
/I If in doubt always assume the destination is a folder e.g. when the destination does not exist. /Z Copy files in restartable mode. If the copy is interrupted part way through, it will restart if possible. (use on slow networks)
/Q Do not display file names while copying.
/F Display full source and destination file names while copying.
/L List only - Display files that would be copied.
Destination Options
/R Overwrite read-only files.
/T Create folder structure, but do not copy files. Do not
include empty folders or subfolders. /T /E will include empty folders and subfolders.
/K Copy attributes. XCOPY will otherwise reset read-only attributes. /N If at all possible, use only a short filename (8.3) when creating
a destination file. This may be nececcary when copying between disks
that are formatted differently e.g NTFS and VFAT, or when archiving
data to an ISO9660 CDROM.

/O (Windows 2000 only) copy file Ownership and ACL information.

/X Copy file audit settings (implies /O).XCOPY will accept UNC pathnames

Examples:

To copy a file:

XCOPY C:\utils\MyFile D:\Backup\CopyFile

To copy a folder:

XCOPY C:\utils D:\Backup\utils /i

To copy a folder including all subfolders.

XCOPY C:\utils\* D:\Backup\utils /s /i

The /i defines the destination as a folder.

Notes

In many cases the functionality of XCOPY is superseded by ROBOCOPY.

To force the overwriting of destination files under both NT4 and Windows2000 use the COPYCMD environment variable:
SET COPYCMD=/Y
This will turn off the prompt in Win2000 and will be ignored by NT4 (which overwrites by default).

When comparing Dates/Times the granularity (the finest increment of the timestamp) is 2 seconds for a FAT volume and 0.1 microsecond for an NTFS volume.

The WinXP version of XCOPY will accept wildcards for the source e.g. *.txt
It is also more forgiving with trailing backslashes
