Robocopy

Eg. MOVES a folder and sub-directories without waiting and without retrying, strips off the security.
robocopy \\from\this\dir \\to\this\dir /e /zb /copy:DAT /r:0 /w:0 /mov

robocopy "E:\source\subfolder" "Q:\target\subfolder" /e /zb /copy:DAT /r:0 /w:0 /move

Note: if you are going to save this as a batch file, don’t call the batch file Robocopy.bat!
…and watch your speech marks. Word destroys them!
