How to maintain user's local data when updating MSIX app

[DevelopW]

I'm building an MSIX app and distributing the app on the Microsoft Store. My MSIX app stores the user's individual software settings in text files in the %APPDATA% folder.

However, with MSIX apps, it seems that all the data in the %APPDATA% folder is deleted when the app is updated from version 1.00 to version 1.01.

Is there a way to update the MSIX app while preserving these local data?

Hi @DevelopW 
This behavior is unexpected. By design, for MSIX apps, the App Data doesn't get deleted during update.
Please share more information about the app that you're trying to build so that we can investigate further.

Thanks,
