Answer 1

You may try this:

import shutil

new_root = r'C:\Users\me\new_root'
root_with_files = r'C:\Users\me\all_of_my_pdf_files'

for root, dirs, files in os.walk(root_with_files):
    for file in files:
        if file.lower().endswith('.pdf') :  # .pdf files only
            shutil.copy( os.path.join(root, file), new_root )

Answer 2

Your code doesn't move any files to new folder. you can move your files using os.replace(src,dst) .

try this:

new_root = r'C:\Users\me\new_root'
root_with_files = r'C:\Users\me\all_of_my_pdf_files\'

for root, dirs, files in os.walk(root_with_files):
    for file in files:
        os.replace(os.path.join(root, file),os.path.join(new_root, file))
