Do files stored using the file system module persist after app updates


This is a question I should know, but somehow haven’t ran into this situation over the years.

Question—do files you persist using the core file system module remain after the user installs an update from Google Play or the App Store?

I’m building a very simple app where I just want the user to essentially a few settings. I don’t want to use application settings because I want the settings to remain after the user closes the app, and I also want the settings to remain after the user updates as well.

Any help would be appreciated. Thanks! :slightly_smiling_face:


Application Settings remain after user closes the app, mostly even after installing updates. At least in Android the backup feature makes application settings available even after re-installing the app.

And Yes, files stored in documents directory must be persist.
