Just it, Enjoy the below article....
Let me paint you a picture:
You're doing a little digital spring cleaning, and you realize you've got triplets of the same file:
- invoice_final.pdf
- invoice_final_v2.pdf
- invoice_final_2_REAL_FINAL.pdf
Or worse… you downloaded the same meme 17 times in 2 years.
You don't want to be a hoarder, but your files say otherwise.
So here’s what I did:
I built a simple, powerful Python script that finds and removes duplicate files — even if they have different names.
And yes, I now sleep better at night.
? The Pain: You Don’t Know What You Have Anymore
You back up your stuff. You organize things (well, once).
But then: cloud syncs, Slack downloads, renamed copies, and panicked backups all pile up.
Suddenly:
- Your storage is full
- You can't find things
- You're afraid to delete anything in case it's "the important version"
The Cure: Check Files by Content, Not NameForget filenames.
The secret is to check each file’s hash — its digital fingerprint.
If two files have the same hash, they’re identical.
Even if one is called resume.pdf and the other is copy-of-resume-2022-old.pdf.
Let’s do it.
? Step-by-Step: The Python Script That Sniffs Out Duplicates
Step 1: Calculate a file's hash
import hashlib
def file_hash(filepath, chunk_size=8192):
hasher = hashlib.md5()
with open(filepath, 'rb') as f:
while chunk := f.read(chunk_size):
hasher.update(chunk)
return hasher.hexdigest()
This reads a file in chunks and builds its hash. MD5 works fine here — we’re not encrypting nuclear secrets.
Step 2: Scan a directory for duplicates
import os
def find_duplicates(folder):
hashes = {}
duplicates = []
for root, _, files in os.walk(folder):
for file in files:
path = os.path.join(root, file)
try:
filehash = file_hash(path)
if filehash in hashes:
duplicates.append((path, hashes[filehash]))
else:
hashes[filehash] = path
except Exception as e:
print(f"Skipped {path}: {e}")
return duplicates
Step 3: Use it and print results
if __name__ == "__main__":
folder_to_scan = os.path.expanduser("~/Documents")
dupes = find_duplicates(folder_to_scan)
if dupes:
print("Found duplicates:")
for dup, original in dupes:
print(f"{dup} == {original}")
else:
print("No duplicates found!")
? What You Just Got Back
This script:
- Works on any folder
- Finds real duplicate files
- Ignores names, cares about content
- Shows you which files are taking up double space
You can even tweak it to:
- Auto-delete duplicates
- Log everything to a file
- Sort duplicates into a ~/Duplicates folder
I found tons of smart ways to extend this script on . Especially under:

Worth bookmarking — I keep it open like a daily command center.
? Final Thought: Clean File Life = Clear Mind
You don’t need a rocket launcher app.
You need small scripts that fix annoying things. That actually give you back time and brain space.
Start small. Keep it weird.
Python can do a lot more than fetch weather data — it can declutter your life one hash at a time.
Want a version that runs automatically every week? I’ve got a version that does just that — happy to share it.
And if you're the kind of dev who likes collecting quirky little problem-solvers, is where I usually find ideas, tools, and inspiration that don’t make me snore.
Stay tidy, my friend. ??
