RollScrub, Duplicate Photos With Receipts

Field notes

The documented scan accepts several folders or volumes at once, then narrows candidates by exact size and head-and-tail signatures before reading surviving files end to end. The interface exposes both paths, file sizes, dimensions, capture dates, and full-size previews, with keyboard controls for large review sessions. A sample command-line run reports 48,207 files scanned and 214.8 GB reclaimable; the page also shows a visually similar pair rejected after byte-level verification.
