For an explanation of the front file just fire up a terminal window and type "df". Yep, that's right, your NeXT is now equipped with a new filesystem type, a swap filesystem. One feature of this is that you can see the swaptimizer in action, the difference in size twixt swapfile and swapfile.front shows you how much compression you're getting on your swap space. Scotty
