Anyone who uses a computer on a regular basis will have personal information of some kind stored on it, whether it's a personal computer or one used at work. Most files and folders that you have stored may not be overly private but you will have private or sensitive information you will need to keep secure. The easiest way to keep this data secure is to use a file security program, that way you can hide, encrypt and lock folders on your computer. 18 Dec 2008
