Archive files (photos/screenshots/videos etc). I have when I have 1000+ files in a single directory

archive.py

#!/usr/bin/env python3

import os
from datetime import datetime
from multiprocessing import Pool

def is_image(x):
    return x.endswith('.jpg') or x.endswith('.png')

def is_movie(x):
    return x.endswith('.mp4') or x.endswith('.webm')

files = [f for f in os.listdir('.') if is_image(f) or is_movie(f)]

def move_file(filename):
    mtime = int(os.stat(filename).st_mtime)
    dirname = datetime.utcfromtimestamp(mtime).strftime('%Y-%m')
    if is_movie(filename):
        dirname = f'{dirname}-video'
    if not os.path.isdir(dirname):
        try:
            # Not thread-safe, but I don't care
            os.mkdir(dirname)
        except FileExistsError:
            pass
    os.rename(filename, os.path.join(dirname, filename))


with Pool(8) as p:
    p.map(move_file, files)
