If you have 50 of these files and want co compare each file with each other, do you realize how many file comparisons you're going to run? Your computer might happily do it (if your files are not too large), but what are you going to do then with more than a thousand resulting comparisons? Compare each comparison with each other and get half a million results?

Perhaps you should rethink your actual needs.
