Syntax of Xcopy command
Xcopy has a large number of possible switches, which gives the command a great deal of flexibility. The syntax for the command is given by:
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]...]
Upper case letters have been used above but the command is case-insensitive. A description of the various switches is given in Table I. Note that Windows Vista has an additional switch "/B". The function of this switch is to copy a Symbolic Link itself instead of the target of the link. Windows 7 has added "/J" to use unbuffered I/O for large files.
