Google did not help. Nothing I did helped.
Those of you who do any windows scripting may know what I'm talking about.
There is a command called 'xcopy'
To guarentee that you get a completely clean copy you need a few command line arguements.
Specifically /d /i /c /k /h /e /r /f /y ... which would normally be written as /dickherfy
granted xcopy foo /dickerfy makes you wonder who the hell he is.
