In their own words
Dup Detector
Dup Detector is a free, open-source desktop application for finding duplicate files and reclaiming storage space. It runs on Linux, macOS, and Windows. Smart hashing compares file sizes first, then partial content, and performs full content hashing when needed. The maker says smart hashing can scan 10,000 or more files per second. Multithreaded scanning is supported, and the app describes its memory footprint as minimal. Dup Detector identifies duplicates but does not remove them automatically, so users decide which files to keep or delete. The maker says the code is fully open source and welcomes inspection and contributions. It states that the app has no analytics, telemetry, or data collection. The Free plan costs nothing, is available forever, and includes cross-platform use. GitHub issues and Discord provide support and feedback channels.
