Python's pathlib Module: Taming the File System – Real Python
January 11, 2025 - You’re using .with_stem() to create the new filename without changing the extension. The actual copying takes place in the highlighted line, where you use .read_bytes() to read the content of source and then write this content to destination using .write_bytes(). While it’s tempting to use pathlib for everything path related, you may also consider using shutil for copying files.
