Help me with data saving. I'm upadating the app to version 1.0.1 and facing the data saving problem. 1. When it has different saving types between the previous and updating one how can I test data saving function? I'm thinking to bring the copied data from the previous version to the new one. But I don't get how to test it. 2. And is it possible to make another save file from the previous one with a new name? In that case there's gonna be two save files.
