When you create private storage vaults (volumes) in SafeHouse to hold your confidential files, SafeHouse adds a new phantom (virtual) drive letter to Windows to make it easy for you to work with your files.
The reason we chose the approach of working with new Windows drive letters to represent your protected storage areas was to create an unmistakable distinction between your confidential data and any of the other files you may have on your PC. This also makes it easy for us to completely hide all the file and folders names relating to your sensitive files.
We believe our concept makes using a privacy product like ours very simple to understand. You enter your password and a new drive letter appears. Everything you put into that new drive letter is protected. That's all you need to know.
On the other hand, products which attempt to lock individual folders on your standard C drive could confuse users because you might forget which folders are protected and which are not, and you might end up saving a confidential file to a folder which is not secure.
