Progress Finished Question

Well, I've come back to this because, well, why not. I've decided to go the custom copy function route and have come up with this (very rough code--just proof of concept for myself):

import shutil, os, sys

with open('397.64-desktop.exe', 'rb') as f:
    with open('C:\\Users\Mark\Downloads\Ordenador\driver.exe', 'wb') as g:
        size = os.stat('397.64-desktop.exe').st_size
        while True:
            moving = f.read(1024576)
            g.write(moving)
            size2 = os.stat('C:\\Users\Mark\Downloads\Ordenador\driver.exe').st_size
            print('\r', size2 / size * 100)

It works, but needs refinement (BIG time). I've noticed, however, that it is nowhere near as fast as shutil, or native OS copying. How can I improve the speed of transfers. I know of course you're limited to the IO of the drive but in my testing (NVME SSD) it's waaay slower than the drive can handle.

@wavic - I'd love to see code examples. Helps me learn, for one. But in my testing (code is deleted at this point), built-in Python functions halt at the copy/move line until the transfer is complete. Proving me wrong is always welcome.
