XCOPY source [destination] [/A | /M] [/D[:date]] [/P] [/S
[/E]] [/V] [/W]
[/C] [/I] [/Q] [/F] [/L] [/G]
[/H] [/R] [/T] [/U]
[/K] [/N] [/O] [/X] [/Y] [/-Y]
[/Z]
[/EXCLUDE:file1[+file2][+file3]...]
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,
doesn't change the attribute.
/M Copies only files with the archive attribute
set,
turns off 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[+file2][+file3]...
Specifies a list of files containing strings.
Each string
should be in a separate line in the files.
When any of the
strings match any part of the absolute path
of the file to be
copied, that file will be excluded from being
copied. 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.
/P Prompts you before creating each destination
file.
/S Copies directories and subdirectories except
empty ones.

including empty ones.
Same as /S /E. May be used to modify /T.

more than one file,
assumes that destination must be a directory.

/G Allows the copying of encrypted files to
destination that does
not support encryption.

/T Creates directory structure, but does not
copy files. Does not
include empty directories or subdirectories.
/T /E includes
empty directories and subdirectories.

destination.
/K Copies attributes. Normal Xcopy will reset
read-only attributes.

overwrite an
existing destination file.
