During my app's runtime, I'm saving some data in txt file to location: Windows.Storage.ApplicationData.Current.LocalFolder On Windows 10 PC, I can easile read this file in C:\Users\marcin\AppData\Local\Packages[app id]\LocalState\ How can I access this file, when I run the app on a phone? When I connect my device to a PC, I don't see an option to access AppData folder.
To Access App Data, You need Device Portal first. Below are the instructions from MSDN.
Type the IP address displayed below the Device Portal options into your favorite web browser.
Make sure you’ve got an app sideloaded (or sideload one now using the “Apps” page).
