Sorry, didn't see the "expand" button. In that list of fields, should I look for "bytes written"?

And with print(len(result)) I'll know the size but once downloaded, I need to know how it goes, how many bytes I downloaded, and how many remaining...something like that so the user can know if need to cancel because it's trying to download 3Tb or it's downloading 200MB and is just a slow connection.

Thanks!
