Windows 10 is a work in progress and Microsoft updates every bit of it and adds new features.
Sometimes some new features are hidden and you need some special tricks to access them.

One of these hidden features is the addition of the UWP File Explorer.

To access the new UWP Explorer on Windows 10 you can right click on your desktop, choose “New” and then create a shortcut and as its target, enter this:
explorer shell:AppsFolder\c5e2524a-ea46-4f67-841f-6a9465d9d515_cw5n1h2txyewy!App

Now you have an easy way of accessing the new UWP File Explorer, that is normally only accessible on Windows Mobile 10.
