It's very simple. Then you have a salvagable file > system. A complete foolproof car is a car with a maximum speed of 0 mph. As a user I give commands to my computer, for example an order to delete a file. And this is what I expect it to do. If I want it to move a file to another position in the filesystem, I would use another command. I don't want my operating system to josh me, that's why I use Linux. Stealthy keeping of deleted files somewhere is a security black hole. But accidents happen. Hardware perishes, users are making mistakes, sometimes coffee is pouring... That's why we backup important data regulary. A not-really-deleting-filesystem wouldn't relieve us of that duty, but would make a system more insecure and ambiguous. Lew
