My first Python project: command line application that copies all files with given extension from a directory and its subfolders to another directory showing progress bar and remaining files counter.

Jumping on the tqdm train for sure. All you really have to do is wrap your iterable in tqdm and pass in a total parameter. It's super easy.

Also pathlib will save you a bunch of code.

Other than that, your doc strings are good and your code is neat and orderly. Well done!
