XCOPY windows command
There are different operators that you can use with the Windows XCOPY command, which was discussed in this Tip of the Night. See the list on the Windows site here. So for example if you enter this command in a .bat file:
xcopy C:\MyData E:\NewFolder /y /e /s
. . . the operator /y will copy data without prompting the user to answer yes or no as to whether or not she wants to overwrite files. /s copies data from directories and subdirectories. Adding '/e' will copy the subdirectories even if they are empty.
