I've got a WPF app that writes data to %appdata%. I understand the writes get redirected to a per-app location, but I want to have a menu option in my app to open the folder with the app data. As far as the app is concerned, it's writing to C:\Users\myusername\AppData\Roaming\VidCoder-Beta\ but it's actually writing somewhere else. However when I try to open an explorer window it goes to the first location (where the data isn't). How can I get the actual write location from inside the app?
UWP apps store their appdata in a subfolder located in
C:\Users\username\AppData\Local\Packages
This should be where your app is now storing its data, under a subfolder that is most likely named with a random set of characters. To find out which random folder your app is, look in the Packaging section of the application manifest. (Package.AppXManifest). The "Package Family Name" should be part of the name of your app's appdata folder, as in this image. Once you've found the folder, local data is stored under the subfolder LocalState, roaming data under the folder RoamingState.
