"Secret Garden is a personnel data encryption software by using encryption algorithm(128bit) and Virtual Hard Disk Drive technology. This software allows you to manage whole encrypted data easily and conveniently because it is working as same as physical hard disk drive and mapping unused drive letter from D to Z drive automatically. In case of other applications, almost any of them uses converting software to save and back-up the files. However Secret Garden adopts Virtual Disk Drive to install and save not only normal data files but also all kinds of application that needs to be encrypted."
