General Manager of Core Ux for Windows Desktop, Tablet and Phone Peter Skillman confirms on Twitter that Microsoft is working on a "total update" of File Explorer, the default file manager application that lets you navigate the contents of Windows.
@HUGEMSFAN Yes we are working on a total update of file explorer! Can't articulate schedule yet. You are right.— peter skillman (@peterskillman) March 18, 2016
He later clarifies the tweet was intended to be private and for a Microsoft employee. Nevertheless, the cat is the out of the bag.
