Recommend Data Stash 1.1

Data Stash is an award-winning clever little security tool that allows you to hide sensitive data files within other files. Select a large bitmap or database file (or any file you'd like to use) as a receptacle, then add the data files you'd like to hide, via an easy drag and drop mechanism. The receptacle file remains FULLY functional. Password protection is also provided, using Blowfish encryption.
