This is a Mac app I made for fun sometime in 2013. You just type in a password, and it makes a folder maze of thousands of folders, so you would navigate inside the p folder, then the a folder, then the s folder, and so on if you set password as the maze password. This makes it easy to hide secret files without encrypting. Also, there is an option to prevent spotlight indexing.
It only took me about an hour to make this app. This app does not use the Mac App Store or Developer ID sandbox, so you will have to right click the app to open it.
