This is actually a menu which has options to open another instance of the program, with or without administrator rights.

The ribbon UI has four tabs: Home, Manage, View and Tools. It also shows you the current drive's total space and available free space. The other displays the current folder's properties such as the number of files, folders it contains and their size. There are two bars on the bottom of each pane: the first displays the number of selected files, folders, and their size.

The left and right arrow icons are used to go back or forward a visited folder, while the clock icon pops down with a history of the recently opened folders. The icon with three upward arrows allows you to navigate to the root folder of the current path, the up icon is for jumping up to the previous folder, and the refresh button updates the folders contents. The first 5 buttons on the Exploration bar can be used for the basic file operations: cut, copy, paste, delete to recycle bin and delete permanently. looks nice and provides enough information. I used the first button, which is the details mode because it has the best of both worlds, i.e. There are other views such as Details mode with thumbnails (every icon has a thumbnail and a description), icon mode (which looks like the Windows Control Panel), a list mode and a thumbnail mode (like a grid of icons). It takes a nice chunk of the on-screen real estate, so you may want to use the buttons below the 'Exploration' tab to switch to something like the Details mode that is similar to Explorer's details view.

See that large picture on the top portion of the pane? That's the 3D thumbnail view. You can use it to navigate to different locations,e.g.

The Exploration tab, displayed on top of each file view pane, displays the file tree.
