Immersive Explorer is a modern file explorer for Windows 10, Windows 8.1, and Windows 7.
Immersive Explorer is an alternative to the default file explorer included in Windows (known as Windows Explorer).
Although it is not a Windows Store Application, Immersive Explorer is designed around the "Metro" user interface guidelines. It is optimized for tablets and computers with touch-screens, but it also offers a great experience for mouse/keyboard users (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 Windows File Explorer. Note that it's not a complete replacement for the Windows Shell (it's just an alternative to the Windows Explorer) and it doesn't even need administrator rights to be installed.
