Placing multiple csv files in a common location

Hi Good day,

I have a requirement where I need to place four source csv files in a location . Instead of using the csv formatter and file reader four times , do we have a method of combining all the four csv files and place it in a location . Here each file has different names and also the data present in each file will be different . Please suggest a way so that it could be optimally achieved .

Thanks,
