Audience

Individuals and professionals who need accurate duplicate detection on Windows and macOS: photographers and anyone culling large photo libraries, alongside developers, IT staff and creative teams working with archives, codebases, external drives or NAS volumes.

About DuoBolt

DuoBolt is a high-performance desktop application for finding duplicate files and similar photos, on macOS and Windows.

Exact duplicates are proven byte-for-byte by a multi-threaded BLAKE3 engine — never filenames, metadata or heuristics — across folders, codebases, archives, external drives and NAS volumes, with uniform accuracy at any data size.

A second engine groups photos that merely look alike: bursts, edits, re-saves. AI Curation ranks each group and names every measure it used — face sharpness, exposure, eyes open, framing. It runs entirely on your machine: no upload, no account, no network.

The workflow is intentionally simple:

• Choose the locations to scan
• Review results with clear contextual grouping
• Remove only what you select — deletions go to the system Trash and can be reverted

Free to use. Every download starts with 7 days of Pro; afterwards DuoBolt keeps scanning and showing everything it finds, and caps only what a single operation can move.

Duplicate photo finder "looks" at your photos to find similarities. Find look-alike and duplicate images in a folder, computer, network, or find duplicates in Adobe Lightroom. Organize photos by eliminating useless repeating pictures - save valuable disk space. Identify similar and duplicate images even if they are edited, rotated, flipped, or color-corrected. Specify percent of image similarity that will be used during the scan. It can broaden your results or specify exact match varying only in image format or size. After the scan process is finished the program shows all the duplicate images in groups and can automatically mark the smaller resolution and/or smaller file size images to be delete - the lower quality ones.

The energetic duplicate cleaner, Clone Files Checker, will delete all 'trash' stuff within seconds and you will be able to rescue 10s of GBs of hard drive space without the need to purchase new storage space.

Skimrr
Skimrr is a privacy-first desktop application for macOS and Windows that helps you clean up your photo library by finding exact duplicates, similar shots, and blurry photos. Unlike cloud-based tools, Skimrr processes everything locally on your own machine. Your photos are never uploaded or analyzed remotely, ensuring complete privacy. Key features include: Smart duplicate matching: Identifies exact byte-for-byte copies and visually similar photos (like a RAW file and its JPEG export). Intelligent suggestions: Automatically suggests the best version to keep based on format (RAW > JPEG), resolution, and sharpness. Advanced blur detection: Analyzes images tile by tile to distinguish between a missed focus and an intentional soft background (bokeh). Safe workflow: Files are moved to an internal local trash and can be restored to their exact original folders. Side-by-side review: Zoom in up to 200% across multiple photos simultaneously to compare sharpness.

Videos and Screen Captures

Play Video Duplicates decided by a full BLAKE3 hash — names, dates and folders play no part. Similar photos grouped and kept apart as variants or look-alikes, across five bands of tightness. AI Curation names the best shot in each group and the measures behind the choice. Every batch passes a review screen before anything moves to the Trash, an archive or a copy. APFS clones are reported as 0 B recoverable, so the figure shown before a delete is the space the disk will actually free. Quick picks, exclusions and a size range, with scans that resume where they stopped.

Threshold-based alerts flag problems early, so your team can act before users notice, not after.

Reactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.
