Keeping your files secret

There are many ways to store our files safely and securely. One way is to just encrypt each file with a strong encryption method (e.g 256-bit AES). Another way is to create a virtual drive that encrypt the whole files in it. There are some softwares for the second method. One of them is PGP Desktop (non-free), and another one is TrueCrypt (GPL, downloadable from http://www.truecrypt.org/)
