Simulate Xcopy's function instance code

xcopy is copy extension, you can copy the specified directory files and directory structure, but cannot copy system files, use the source drive, source destination pathname, source file name at least one, select/s when the source directory and all the files under the subdirectory copy. Unless you specify the/e parameter,/s does not copy an empty directory, and if you do not specify the/s parameter, xcopy copies only the files of the source directory itself, not the subdirectories below it, and when you choose the/v parameter, the copied sectors are checked, but the speed decreases.
