Microsoft just announced the new Fluent Design language, formerly known to us as Project NEON.

In the promo sizzle reel, various concept images flashed up for new user experiences based on existing apps, including Mail, the Store, and more. But one of the most intriguing was this radical overhaul for the Windows File Explorer.

These images are just concepts, at least for now. The File Explorer has remained unchanged for years, but this clip could give us an idea of where Microsoft might take one of Windows' most static features in the future. Here's the full video, the concept flashes up towards the end.

Stay tuned to Windows Central for all the latest from Build 2017.
