Blacksheep, a useful tip indeed, but it will only work with cameras which are recognised by Windows as 'USB mass storage'. Canon is one of the manufacturers who doesn't use this method, and although the camera will still show up in 'My Computer' I cannot transfer files to it. These cameras use PTP (Picture transfer protocol) to connect to and communicate with the 'puter, and this only allows images and movie files to be copied from camera to computer.
