Portable Vault by StompSoft is everything that I expected and more. I purchased this software to secure data on my USB drive. I expected some difficulty initially and was a little worried about whether I would have a hard time learning how to use it. Well these thoughts could not be further from the truth. The interface is clean and straightforward. The whole process is very intuitive and easy to follow. Between the blowfish encryption and the automatic conversion of files I feel that this product is best it can be.
