Honestly the best thing to do is to move the entire files off, I think any management file app on Android has the app flies. I can see mine but I don't really going to touch much of it.
Only some app files have stuff in them. I think it depends on save types. I'll just either wait until it's possible to transfer it or just Start over. I still plan to use the old device for as long as I can anyway, so it's not urgent nor super important.
