c:\users\administrator>xcopy/? Copy files and directory trees. XCOPY source [Destination] [/a |/M] [/d[:d ate]] [/p] [/S [/E]] [/v] [/w] [/C] [/i] [/q] [/F] [/                           L] [/g] [h] [/R] [/T] [/u] [/k] [/n] [/O] [/x] [/y] [/-y] [z] [/b] [/j]  [/exclude:file1[+file2][+file3] ...]  SOURCE specifies the file to be copied.  destination Specifies the location and/or name of the new file.  /a copies only the files with the archive property set, but does not change the properties.  /M copies only files that have an archive attribute set and closes the archive attribute.               /d:m-d-y copies files that change after a specified date or a specified date.  If no date is provided, only those files that have the source time newer than the target time are copied.               /EXCLUDE:FILE1[+FILE2][+FILE3] ... Specifies a list of files that contain strings. Each string should be on a separate line in the file. If any string matches any part of the absolute path of the copied file, the file is excluded from being copied.  For example, specifying a string such as \obj\ or. obj excludes all files under directory obj or all files with the. obj extension, respectively.  /p prompts you before creating each target file.  /S copies directories and subdirectories, not including empty directories.               /e copies directories and subdirectories, including empty directories. Same as/s/e.  Can be used to modify/T.  /V verifies the size of each new file.       /w    Prompts you to press the key before copying.  /C Continue copying even if there is an error.  /I if the target does not exist and you want to copy more than one file, assume that the target must be a directory.  /q does not display the file name when copying.  /F Displays the full source and destination file names when copying.  /L Displays the files to be copied.  /g allows encrypted files to be copied to targets that do not support encryption.  /h also copies hidden files and system files.  /R overwrites read-only files. /T Creates a directory structure, but does not copy files. Empty directories or subdirectories are not included.  /T/E includes empty directories and subdirectories.  /U copies only files that already exist in the target. /k Copy Properties.  General Xcopy resets the read-only attribute.  /n is copied with the generated short name.  /o copies file ownership and ACL information.  /x Copies the file audit settings (implied/O).  /y Cancel the prompt to confirm that you want to overwrite the existing destination file.  /-y to be prompted to confirm that you want to overwrite the existing destination file.  /z copies network files in restartable mode.  /b Copies the symbolic link itself and the link target. /j does not use buffered I/O when replicating. It is recommended to use when copying large files. The switch/y can be pre-set in the COPYCMD environment variable. This may be overridden by the/-y on the command line.
