Portability is something that many computer users take advantage of, USB devices are a quick and easy way of storing and transferring data between numerous machines. Hugely convenient and fairly cheap, modern USB drives store a reasonable amount of data and are small enough for you to take on the road. The trouble with all this data moving back and forth is that recognising recently edited and saved documents can become a little trickier, especially as drives become larger. 30 Oct 2008
