Hi HN, I built a duplicate file finder for my brother who's a photography enthusiast and constantly runs out of storage constantly due to resizing a lot of photos and having a lot of duplicates around. Notes: - Incremental hashing: Instead of loading entire files into memory, I hash files in chunks. Files with identical sizes get grouped and progressively hashed until they diverge or match completely. - Perceptual hashing: For images, I use perceptual hashing (pHash) that generates a fingerprint based on visual content rather than bytes. Similar images have similar hashes. - BK-Tree…
