@Rokebo73 Having more backup options in OneDrive is a different discussion and not at all the root cause of this specific problem. The documents folder is NOT supposed to be a dumping ground for non-user generated data and DICE is simply not following programming practices. I can see it making sense that save files go under Documents/Save files/Battlefield.
However, one could argue that Microsoft is too lenient in this, not enforcing software developers to follow the guidelines. Make a quick google and you'll see that DICE are unfortunately not alone, and generating many users upset about this lazy-developer behavior. Who's to blame, MS or the developers? I'd say both. But until MS does something about it, I'm still expecting big and renowned companies like DICE to follow best practices.

I just noticed that there's an exclusion option in OneDrive, I just set it to exclude PcDx12. Will see how it goes and update everyone.
