Thank you for responding to my question. I agree--the jam rules should include the link you list here. I bet not many people know about this. It'd be good to know this 200MB single file limit information ahead of time. I knew about the 1GB limit but not the 200MB. My first upload of my game had no problem, but the update of my final finished game only a few hours before the jam closed had the error about the data file size. That was really panicky.
