With this encryption tool, when used wisely, your files will be on steroids!
Actually no, it's just an awesome encryption tool. Why is it awesome? well first it is opensource, comes for windows AND linux. With it you can encrypt whole partition or just make a container where you put all the files - and that one is my favorite. It has all sorts of encryption algorithms.
I've been using it for a looong time and I've been nothing but happy, feeling secure, specially good for laptops
