Glen's mother has a PC running XP and is worried about Microsoft discontinuing support. So he's moving her data over to another computer. Leo says that the best way to move the data over is with a simple thumb drive and Windows Explorer to drag and drop. Then he can run the File and Transfer Wizard to get the rest.
Just because XP will stop being supported after April 8th doesn't mean he has to stop using the computer. He should just make sure it's disconnected from the Internet. Leo also advises getting TeraCopy. There's also RichCopy, which is a third party interface for Robocopy, which otherwise can only be used through the command line.
