How to secure your files and data by not just password protecting them

Using passwords to protect one's files and data is overall good security but for added and better protection one should encryp them. Vista Enterprise and Ultimate editions come with BitLocker Drive Encryption which is a tool relying on a Trusted Platform Module to secure the access to your files and data.Some early users of Vista might need a BIOS update. To enable this one would need an extra partition on the hard drive which you can create with the Vista partitioning tool on your installation disc or with the BitLocker Drive Preparation Tool, a Vista Ultimate Extra. You should create one small partition for essential OS files, and the rest of the drive will hold encrypted files.
