Not all top-secret documents come in digital form. Consider scanning every set of documents you have and storing them on a hard drive or a USB device, encrypting them too, of course. You should then find a good hiding place for these devices in case you are being followed or spied on. Good hiding places do not have to be safes or bank lockers; you could also use USB devices so small that they fit into pens or earrings. Just be creative where to put your sensitive information, and do not forget your chosen hide-out!
