Often in our web app a lot of logs, reports or forms are downloaded through Step Builder "Handle 'Download' dialog".

We would like to compare the downloaded file (xls, xlsx, pdf are mostly used) to a baseline file so that we can verify the downloaded file has the same content as expected result.

This definitely can be achieved through "Coded Step" but it will be great if there is a built in function to compare and verify file, similar to how to verify image.
