Review: GDrive.NET UWP - Google Drive and Photos
(All About Windows Phone)

Yes, this is Google Drive and Google Photos - except it`s not programmed by Google, but by a Windows 10 third party developer instead. GDrive.NET has in fact been around as a WP8.1 application in various forms for a few years and functionality was always a bit hit and miss, but the last few months have seen both a full UWP version and lots of bug/API fixes. It`s now ready to be reviewed, giving you some of the best of Google as well as can be expected on a rival (and different) platform.
