Duplicate File Finder is a free, closed-source Windows desktop application (Windows 10/11, 64-bit) published by Filzyx. It finds redundant files using four independent engines: exact matching over SHA-256, perceptual hashing for photos that were resized or saved again at lower quality, tag-based matching for music libraries, and audio-fingerprint matching that identifies the same recording in different formats or bitrates. The program reports matches live during the scan, previews images with EXIF information, plays audio before deletion, never auto-selects files, and defaults to moving duplicates to the Recycle Bin. Distribution is a standalone Inno Setup installer from the project website. No advertising, no accounts, no telemetry.
