SSIS, Looping text file and Decision making

Hi all,  I have 3 text files (.txt) in the folder "d:\testfolder\" .

1. Student20170201.txt
2. Class20170201.txt
3. Subject20170201.txt

I need to loop all the text files in the given folder and store them accordingly to their specific tables(sql).

How can I achieve this using SSIS package. Thanks.!
