I guess it depends on the need in regards to what we are doing. Presently, I am finalizing some tests in regards to a robot procedure which replaces some old code. So, I need to validate the generation of that one against the old one. On that one, I agree such tool is mandatory. I wouldn't want to open the file one by one and start comparing the bytes and so on.
