DupShelfDupShelf
Exact duplicate photo finder (byte-for-byte)
DupShelf finds exact duplicates only: files with identical content. That is the safest cleanup pass because every grouped file is provably the same as another.
Exact vs similar photos
Resized crops, filters, and re-encoded JPEGs are not matched yet. We group true copies, re-exports, and the same image saved as PNG and JPG when bytes match.
Why SHA-256
A cryptographic hash of file contents is fast to compare and avoids false positives from thumbnails or filenames.
Questions
- Will you add similar photo detection?
- It is planned as an optional mode with clear labeling. Exact mode remains the default for safety.
