Creating a cab type file

Does anybody have any idea how I can create a cab type of file. Something those "hacker" people can't just open with some other program. Also how can I encrypt the file? That would prevent people from opening it.

Thanks for your help!

you can use a cabinet manager tool. This tool can download from http://mirrors.telepac.pt/tucows./ad...lcabmannt.html

Please we can improve our program ability together.
