3D fileSpace can give you a bird's eye view of all your files and folders, so you get quick and direct point-and-click access to each of hundreds of items, far more than a regular 2D view can show.
And you can quickly see what is inside multiple nested folders, without having to painstakingly navigate to each one.
You can have a single window composed of multiple panes each showing a Finder folder and the contents of folders inside, so you can keep on hand in a single window all the files and folders you use day to day. And each pane can be quickly expanded into a new full-size window, any time you wish to see the full details. And any 3D window can be turned into a drawer that sits along the edge of the screen taking almost no space yet immediately accessible.
