Awesome, that is quite efficient in the case that all files can be open and printed to at once, good thinking. The 1e6 range was the largest I'll be working with, the smallest being 1e3, meaning 155,247 files. For those I will have to get my original program to work, I don't know if opening that many files at once is feasible.

I am working on getting a while loop to actually loop with a post incremented value, I think I'll try posing about it after a a few more attempts. Good on ya mate! Thanks for the help
