yeah, you are right.. I just misunderstood the request (you want a simple protection and I thought you want a protecting protection).. my bad, and I'm sorry again... your request wasn't something of bad, my fault..
here are some nice programs that my help you
Password Protection System--CD Edition 1.01 (free to try, will add a password to your cds):
CDShield SE 1.0 (20 days trail..Protects your CD against copying and ripping):
you can also just store (without packing the files) the files in a password protected rar or zip or something.. but ofcourse it won't protect from being copied, just from being opened by the wrong guys..
anyways, sorry for being rude..
enjoy m8, and good luck!
