How to Find Duplicate Files in Python and Move Them Effortlessly

Managing files can be a daunting task, especially when duplicates creep into your directories, occupying space and causing clutter. If you're looking to streamline your file management process, learning to identify and relocate these duplicate files through Python can be incredibly beneficial. This guide will guide you through a simple script that finds duplicate files in a designated folder and moves them to another location of your choice.

The Problem: Identifying Duplicate Files

You may have encountered situations where images, documents, or other files are duplicated in your folders. Identifying these duplicates manually can be tedious and error-prone. Here’s a brief overview of a script designed to automate this process. Your current code is successful in detecting duplicates but struggles with moving them efficiently. Let's address this issue.

The Solution: A Step-by-Step Guide

We'll enhance your existing script to seamlessly move all detected duplicate files to a chosen folder after you've finished scanning. Here’s how to do it in an organized manner:

Step 1: Initial Setup

You’ve already set up the necessary imports for working with the file system:

Step 2: Prompt for the Source Directory

Use askdirectory() to allow the user to select the source folder containing files to check for duplicates.

Step 3: Iterate Through Files

You need to walk through the directory to check each file. This becomes the core of your duplicate detection logic.

Step 4: Create a Hash Dictionary

Instead of moving files immediately, you'll first create a dictionary that stores the hash of each file. This will help you identify duplicates without moving files right away.
