For those who don't know Robocopy is basically an enhanced version of xcopy that came with DOS and comes as the standard command line tool set. Well with Windows 6 and later versions they put the resource kit tool robocopy in Windows. The advantages of Robocopy over GUI based copy or command line copy is the speed. It uses VSS to copy the file so that way it can transfer faster. For instance I transferred a whole DVD-5 in 2 minutes, over a gigabit ethernet connection. To access it go to a command line and type in robocopy /? and it will give you the options. There are a couple GUI tools for it too so look for those if the command line isn't your thing.
