I would strongly suggest anyone who has important documents to back them up at least to either a thumb drive or an external hard drive since normal hard drives do go bad, also your computer could blow up or be stolen. While working as a tech, especially when I was in the east coast, we did have at least once a month, someone come in for help due to lightning strikes that fired their computer, or they lost their computer, or they dropped their laptop in the pool. Also, I just tried the free program called "folder latch". This is a good program to quickly password protect a folder on your computer that you have sensitive documents. However, also have a non password protected backup in case you forget the password. Also, do this before sending your computer in for warranty repair or before calling a tech to work on it.
