Nah, you cant do it. You can put the files in a rar archive, and password it. Thats the best you can do. Preventing them from being copied is impossible. Why? because discs are meant to be read, and copying is also reading. If you are a programmer, you make the copied files from being used, but you cant prevent copying itself. There are lots of disc protections like safedisc, securom for preventing copied files from being used.
