Исходный путь не существует во время миграции папки с одного ПК с Windows на другой с помощью сценария Python. ⇐ Python

[Anonymous]

Я хочу перенести древовидную структуру папок с одного ПК с ОС Windows на другой, запустив скрипт Python на целевом ПК. Вот код, который я использую:

from datetime import datetime
from pathlib import Path

# =======================
# CONFIGURATION
# =======================

# UNC root of source machine (example: r"\\OLD-PC\C$")
# SOURCE_ROOT = r"D$
SOURCE_ROOT = Path("D:\\")

# Local destination root (almost always C:\)
# DEST_ROOT = r"C:\\"
DEST_ROOT = Path("C:\\")

# Folders to migrate (absolute paths from source C:\)
FOLDERS_TO_MIGRATE = [
r"dgarrard",
r"PNC",
r"Installers",
r"Nufocus",
r"openssl",
r"win-acme",
r"ProgramData\win-acme",
r"Program Files\Inkscape",

# Log file
LOG_FILE = rf"C:\migration_log_{datetime.now().strftime('%Y%m%d_%H%M%S')}.log"

try:

logging.info(f"Copied: {src_file} -> {dst_file}")

# =======================

def main():

logging.info("==== Folder Migration Started ====")

for folder in FOLDERS_TO_MIGRATE:
migrate_folder(folder)

logging.info("==== Folder Migration Completed ====")
logging.info(f"Log file saved to: {LOG_FILE}")

if __name__ == "__main__":
if not os.name == "nt":
logging.error("This script is intended for Windows only.")
sys.exit(1)

main()

Когда я выполняю это с помощью IDLE на целевом компьютере (запуская IDLE от имени администратора), я получаю следующий вывод файла журнала:

Исходный компьютер доступен в сети, его можно просмотреть в файловом браузере Windows на целевом компьютере, поэтому я не понимаю, что делаю неправильно. Кажется, это связано с моим определением томов и/или папок.
