    Great article! I think that many people fail to realize how painful losing your data can be. The options to save important files are really easy and relatively low cost now. I believe that in order to really backup and encrypt your files you should always think of the consequences of others finding the data, and I use encrypted flash drive. The option to control your data anywhere is very simple, and the comfort of using and carrying has no price…

      How is Gili USB Stick Encryption better than Rohos Mini? I ask because it’s unclear. We could read about Rohos Mini advantages in this post… Is it possible to access secure partition on the PC in a public library?
