If you are afraid that someone else data at home or at the office, you should install Safe Disk on your computer.
Safe Disk offers you a highly secure place for your sensitive data. In no time, this software can create a virtual disk that can be hidden or displayed, whether protected or not by a password. For that, you just need to localize your files and specify the letter for your virtual disk (K :, L :, F :, etc.) so that it does the rest. Safe Disk is entirely free and can create a virtual disk up to 2 GB of data.
