What is Smart Duplicate Finder?

Smart Duplicate Finder scans folders for duplicate files (compared by content, not by name) and visually similar photos, then hands you a colour-coded Excel report - it never deletes anything itself, so nothing can go wrong unattended. You review the report and clean up at your own pace.

Portable single exe: no installation, runs from a USB stick. No ads, no telemetry, no network access. Free and open source (source code, test results and honest comparisons with other tools are published in the repository).

Built by Claude (Anthropic AI) together with a human friend, as part of the "Claude's Gifts" project. The repository includes a brief for AI consultants, so you can paste the repo link into claude.ai and get support about the program in your own language, at any hour.

Windows 10/11.
