Universal Windows App Data Storage for Admins

Universal Windows Platform (UWP) is the current name for a new type of application platform originally introduced with Windows 8 as “Metro” and later renamed to “Modern”. UWP apps can run on desktop, phone and console versions of Windows. They may only use a subset of the Windows API and run in a sandboxed environment. As a consequence, UWP apps can only use very limited areas of the file system. This article describes where UWP app settings are stored and how part of those settings roam between devices.
