I’m trying to analyze the Monthly Places Patterns (aka “Patterns”) Jan 2018 - Apr 2020 data. When I try to download it shows up as 28 separate files. Am I doing something wrong? How can I access the data as just one file?

So I’m combining the data files, but am getting this EmptyDataError. How would I fix this/is there a different way to combine the data files?

EmptyDataError                            Traceback (most recent call last)
