Python Duplicate File Finder GUI Project 🔥 Find & Delete Duplicat Files
About this video
Learn how to build a complete Duplicate File Finder using Python with a professional GUI.
In this project, we create a Python application that scans folders, detects duplicate files using file size + SHA-256 hashing, displays duplicate groups, and allows users to safely remove unwanted duplicate files.
This is an excellent Python project for students, beginners, computer-course learners, and anyone interested in practical Python automation and OS module projects.
What You Will Learn
Python os module
os.walk() for recursive folder scanning
File and folder handling
os.path.getsize()
os.path.join()
SHA-256 hashing with hashlib
Detecting duplicate files
Tkinter GUI development
Treeview tables
File deletion
Recycle Bin integration using send2trash
Multithreading in Python
File-size formatting
Building practical Python utilities
Duplicate Detection Logic
Select Folder
↓
Scan Files using os.walk()
↓
Group Files by Size
↓
Identify Possible Duplicates
↓
Generate SHA-256 Hash
↓
Compare File Hashes
↓
Display Duplicate Groups
↓
Remove Selected Duplicate Files
The program does not simply compare filenames.
Even if files have different names such as:
photo.jpg
photo-copy.jpg
IMG001.jpg
they can still be identified as duplicates if their contents are identical.
Technologies Used
Python
Tkinter
OS Module
Hashlib
Threading
Collections
Send2Trash
