...]
source Specifies the file(s) to copy.
destination Specifies the location and/or name of new files.
/A Copies only files with the archive attribute set,
but doesn't change the attribute.
/M Copies only files with the archive attribute set,
and clears the archive attribute.
/D:m-d-y Copies files changed on or after the specified date.
If no date is given, copies only those files whose source
time is newer than the destination time.
/EXCLUDE:file1...
Specifies a list of files containing strings. Each string
must be in a separate line in the file. If any string matches
the full path of the file to be copied, that file will not be copied.
For example, specifying a string like \obj\ or .obj will exclude
all files under directory obj or files with the .obj extension.
/P Prompts for creating each destination file.
/S Copies directories and subdirectories except empty ones.
/E Copies directories and subdirectories including empty ones.
Same as /S /E. Can be used to modify /T.
/V Verifies each new file.
/W Prompts you to press a key before copying.
/C Continues copying even if errors occur.
/I If destination does not exist and copying more than one file,
assumes that destination is a directory.
/Q Does not display file names while copying.
/F Displays full source and destination file names while copying.
/L Displays files to be copied.
/G Allows copying unencrypted files to destinations that do not support encryption.
/H Copies hidden and system files also.
/R Overwrites read-only files.
/T Creates directory structure but does not copy files.
Does not include empty directories or subdirectories. /T /E includes
empty directories and subdirectories.
/U Copies only files that already exist in destination.
/K Copies attributes. Normal Xcopy resets read-only attributes.
/N Copies using generated short names.
/O Copies file ownership and ACL information.
/X Copies file auditing settings (implies /O).
/Y Copies file auditing settings (implies /O).
Existing destination files.
/-Y Causes prompting to confirm rewriting an
existing destination file.

The command-line switch /Y may be preset in the COPYCMD environment variable.
This may be overridden with /-Y on the command line.
