Immersive Explorer is designed to be an alternative to the default file explorer included in Windows (known as Windows Explorer).
It aims to provide an "immersive" experience to the user by focusing on the content rather than hiding it behind useless icons and large window chrome and borders. It will also avoid the user from having to open different applications and navigate between multiple windows when doing things as simple as viewing a picture.
For example, when the user want to see a photo, instead of opening Windows Photo Viewer in a new window, the photo will be displayed directly in the Immersive Explorer window.
Although it is not a Windows 8 "Metro application", it is designed around the "Metro" user interface guidelines. It will be optimised for touch-screens, but will offer a great experience for desktop users too (with features like scroll-to-zoom, keyboard navigation).
Immersive Explorer is based on Win32/.net/WPF (Windows Presentation Foundation). It uses graphical hardware acceleration to display fluid animations and transitions, making it look more modern than the default GDI-based Windows file explorer. Note that it is not a complete replacement for the Windows Shell (it's just an alternative to Windows Explorer) and it won't even need admin rights to be installed.
As it is not based on WinRT, unfortunately it means that it won't work on Windows RT devices (but it will work on Windows 8 tablets like Surface Pro). I expect Windows 8 (x86) tablets to be more popular than Windows RT tablets among power users, so lack of Windows RT support is not a huge problem.
Configuration required :
Windows 7 or Windows 8
A Core 2 Duo processor, or better (this app will be optimised to run on low end CPUs like Intel Atom or AMD Fusion in a future version)
At least 1 GB of ram
The .NET Framework 4 must be installed (it is already installed by default in Windows 8, but not on Windows 7)
