When you plug the camera to your USB port and switch it on, there should appear a new drive in MyComputer, labelled Sony Memory Stick. That's the way it works for me. If you have autorun enabled additionally an autoplay handler comes up asking you what you want to do - open the folder, or display the pictures or whatever. There are usually no extra drivers needed for XP.
thanks yo yo / da boss it does that when i connect the camera but if i take the memory stick out it plgs straight into the memork stick reader saving my batteries that after a format needs drivers and i cannot find my disc hence previous post
