dupeGuru vs Gemini 2

dupeGuru is a free, open-source duplicate file finder for Windows, macOS, and Linux. It scans folders by filename or file content to identify exact duplicates, and includes a dedicated Picture mode that finds visually similar images even when they differ in resolution or format. A Music mode adds tag- and metadata-aware scanning for audio libraries, while a customizable matching engine, reference-folder logic, and filtering tools let users review results carefully before choosing to delete, move, or copy the duplicates it finds.
