Czkawka GitHub Overview: How Hashing Finds Duplicate and Similar Files
czkawka by qarmin: qarmin/czkawka
Czkawka is a Rust-based storage analysis project for finding exact duplicates, similar media, and structural file-system clutter while keeping the final decision with a human reviewer. This illustrated overview uses a theoretical Producer_Sample environment to explain why file names and byte sizes alone create false positives, how included and excluded paths define scan boundaries, and how a reference path protects baseline files from bulk selection.
The walkthrough follows exact duplicate detection from size grouping to first-and-last 2 KB Blake3 prehashes and full-file verification. It then contrasts binary hashing with perceptual image matching: images are reduced to grayscale grids, luminance patterns become bit strings, and Hamming distance forms similarity candidates that still need visual confirmation. Empty directory trees, null-byte files, grouped results, path and regex selection, and the transition from computation to human review round out the analysis. The project history also places the legacy GTK frontend's deprecation at version 12.0 and identifies Krokiet as the Slint-based successor.

4:48 Size Grouping, Pre-Hashing, and Blake3 Verification
6:19 Perceptual Hashing for Similar Images
7:37 Empty Directories and Null-Byte Files
8:34 Review Groups and Bulk Selection Logic
9:46 Human Verification Before Cleanup
10:14 Czkawka's Analytical Tradeoff
🧭 Storage entropy, scan boundaries, and reference paths
🔐 Size grouping, Blake3 prehashing, and exact duplicates
🖼️ Perceptual hashing, image similarity, and false negatives
🗂️ Review groups, file-system rot, and human verification
Czkawka is best understood as a reconnaissance and review tool: exact hashing confirms binary duplicates, perceptual hashing surfaces similar media, and reference paths keep baseline files outside bulk selections. The final decision remains human, especially when similarity thresholds or deletion candidates require context.

照片备份了好几轮，文件名也改了，想清重复的又怕删错。 Krokiet 能按内容找重复，免费开源，有中文。 拿4个样例文件试了：3份改名副本归成一组；另一张同名、不同内容的图没有混进去。 先核对，再移到回收站，别直接全删。 qarmin/czkawka t.co
