@phlipelder I thought that those files were necessary. I guess I will try to block them as long as it doesn't cause issues on the Mac side.
I don't know if they are critical or not. From what I see online files like .DS_Store is just to show metadata to the mac client. This is likely the tag color etc for the Mac Finder, which for me (personally) doesn't matter. But I'm sure it would affect business pretty heavily.
