Microsoft's upcoming Cortana-powered Office Work Assistant was revealed in a series of leaked images over the weekend, and now there's a video highlighting the functionality of the app. The video shows how Work Assistant can be launched via Cortana, and can then search for files stored on multiple locations, including your phone, OneDrive, OneDrive for Business, PC and SharePoint.

Using voice commands within Work Assistant, you can find, open, view, edit and load files based on several metadata points. There's also the ability to share files with your contacts via email with either a specific contact or a group of individuals.

At this stage, there's no information as to when Work Assistant – which is in a closed beta on the Windows Phone store – will be made available to the public.
