A *truly* Random Folder

random_folder.py

import glob
import random
import shutil
import os
import pickle

## Make an empty folder called Random and put it on your desktop
## Make an empty file called all_my_files.txt and put it in the same dir as random_folder.py
## Replace my file paths with yours

pathToRandom = '/Users/YOURUSERNAME/Desktop/Random'
pathToAllFiles = '/Users/YOURUSERNAME/WHEREVER/YOU/PUT_THIS_FILE/all_my_files.txt'
rootPath = '/Users/YOURUSERNAME/**/*' # this is the path to all the files in your hd

## To run this code:
## 1. Run Part I, then comment Part I out
## 2. Uncomment Part II, then run again and check your Random folder
