Find and Delete Duplicate Files Using Hashing in Python

Walk a directory tree, compute SHA256 hashes for every file, and delete duplicates that share the same hash.

deduplication files hashing

import os
from pathlib import Path

def file_hash(path, block_size=65536):
    """Return SHA256 hash of file content."""

        while chunk := f.read(block_size):
            hasher.update(chunk)
    return hasher.hexdigest()
