If you want to have your files locked up so no one else can access your file. I found this program called TrueCrypt which is the best, better then the programs then all other encryption programs.
AND IT'S FREE, it's a opensource program which it a good thing, which means that the program it so beaten down to death, so its bug free.

ok, I didn't found it. It was on "Call for Help" some of you people might know it, Hak.5 was on, I found out Hak.5 on that show, and I bet some of you people found out this place on "Call for Help" too.
If you don't know "Call for Help", the hosts were on Hak.5 ep. 6, Leo Laporte, Amber MacArthur, Mikey, etc. If you don't understand tech enough to understand Hak.5, then watch call for help, it is ment for people who doesn't understand tech.
