Move Files based on partial Match

[snippsat]

Use Code tags.
Your description most have been basic and leaving out the 5000 part.
An other problem if don't know Python,then it can be hard to fix or suggest a update from ChatGPT.

Something like this and using pathlib

from pathlib import Path
import shutil

dir_find = '5000'
source_folder = Path("G:/div_code/Source")
des_folder = Path("G:/div_code")
des_subfolder = des_folder / dir_find
for file in source_folder.glob(f"{dir_find}*"):
    # Create the des subfolder if it doesn't exist
    des_subfolder.mkdir(parents=True, exist_ok=True)
    des_file = des_subfolder / file.name
    # move file can also use .copy
    shutil.move(file, des_file)
