Does anyone know of a usb device that you can map a folder on say a laptop and with a cable and a little black box (the usb device), you can plug into a desktop and have the laptop folder appear as a drive under win explorer on the desktop. I hear the question being asked 'why don't you just network them and map the folder as a drive'. This situation exists under a company domain where ms active directory is used so network adjustments are not possiable. Basically I want to copy a large file and I don't want to purchase a very large USB Key disk.
