Python/DOS scripts to copy, sort and rename files.

This script clears the  folder, sorts all  files from the  folder, and copies them into  with sequential names like , , etc.

---

Python Script

• The Python script scans the sub‑folder named "images".

• It collects all files ending with ".jpg", sorts them alphabetically by filename, and then processes them one by one.

• Before copying, it deletes the existing "new_images" folder (if present) to ensure no old files remain.

• It creates a fresh "new_images" folder.

• Each ".jpg" file is copied into this new folder and renamed sequentially as "image_001.jpg", "image_002.jpg", ….

• The numbering uses three digits with leading zeros for consistency.

rename.py

import os
import shutil

src_folder = "images"
dst_folder = "new_images"

cwd = os.getcwd()
print("Current Working Directory:", cwd)

# If the target folder exists, clear it first.
if os.path.exists(dst_folder):
    shutil.rmtree(dst_folder)

# make the target folder
os.makedirs(dst_folder, exist_ok=True)

# Get all JPG files and sort them.
files = sorted([f for f in os.listdir(src_folder) if f.lower().endswith(".jpeg")])

# Copy and rename
for idx, filename in enumerate(files, start=1):
    new_name = f"image_{idx:03d}.jpg"   # image_001.jpg format
    src_path = os.path.join(src_folder, filename)
    dst_path = os.path.join(dst_folder, new_name)
    shutil.copy2(src_path, dst_path)

print("Done! new_images has been cleared and all files have been regenerated.")

Windows DOS Batch Script

• The batch script performs the same task but directly in Windows Command Prompt.

• It checks if the "new_images" folder exists; if so, it removes the entire folder and its contents.

• It then recreates the folder.

• Using the "dir" command, it lists all ".jpg" files in the "images" folder, sorted alphabetically.

• Each file is copied into "new_images" and renamed sequentially as "image_001.jpg", "image_002.jpg", … with three‑digit numbering.

rename.bat

@echo off
setlocal enabledelayedexpansion

set SRC=images
set DST=new_images

:: If the target folder exists, delete the entire folder.
if exist "%DST%" rd /s /q "%DST%"

:: make the target folder
mkdir "%DST%"

set /a count=1
for /f "tokens=*" %%f in ('dir /b /on "%SRC%\*.jpg"') do (
    set "num=000!count!"
    set "num=!num:~-3!"
    copy "%SRC%\%%f" "%DST%\image_!num!.jpg"
    set /a count+=1
)

echo Done! new_images has been cleared and all files have been regenerated.
