How can we export test steps into a file (notepad) from setup scripts

I believe that you should use the application appropriately, so that you do not run into such cases.

For instance, setup script is meant for doing something to meet the predefined condition for the test case while automating the tests. And not meant for how you are currently using.

If the software is used in the same fashion as it is intended, everything is smooth and generates test artifacts appropriately.

By the way, if you can tell what are you trying to achieve, that would help to understand the problem better.
