Automate Selective Folder Copying in Python: Two‑Step Script Guide

Introduction

In a Python community a user asked how to automate file copying for large data folders. This article shares a complete solution.

Implementation Process

The original script attempted to copy files but did not meet expectations. The improved approach splits the task into two passes: first copy all directories whose name starts with “数据”, then copy those containing “DD”.

import shutil
import os

def copy_file(path):
    for root, dirs, files in os.walk(path):
        for dir in dirs:
            if "数据" in dir:
                shutil.copytree(root + '\\' + dir, target_path + '\\' + dir)
                print(root + '\\' + dir + ' copied -> ' + target_path)
        for dir in dirs:
            if "DD" in dir:
                shutil.copytree(root + '\\' + dir, target_path + '\\' + dir)
                print(root + '\\' + dir + ' copied -> ' + target_path)

if __name__ == '__main__':
    source_path = r'D:\SupplyChain\Orders'
    target_path = r'C:\Users\Desktop\res'
    copy_file(source_path)

Two separate code snippets illustrate the first‑pass extraction (filtering “数据”) and the second‑pass extraction (filtering “DD”).

Summary

The provided Python script demonstrates how to automate office tasks such as selective folder copying, offering a clear, reproducible solution for the community.
