dupeGuru
dupeGuru is a cross-platform (Linux, OS X, Windows) GUI tool to find duplicate files in a system. It’s written mostly in Python 3 and has the peculiarity of using multiple GUI toolkits, all using the same core Python code. On OS X, the UI layer is written in Objective-C and uses Cocoa. On Linux & Windows, it’s written in Python and uses Qt5. dupeGuru is a tool to find duplicate files on your computer. It can scan either filenames or contents. The filename scan features a fuzzy matching algorithm that can find duplicate filenames even when they are not exactly the same. dupeGuru runs on Mac OS X and Linux. Find your duplicate files in minutes, thanks to its quick fuzzy matching algorithm. dupeGuru not only finds filenames that are the same, but it also finds similar filenames. It has a special music mode that can scan tags and shows music-specific information in the duplicate results window.

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.

FileBricks
FileBricks is a visual disk space analyzer that helps Windows users quickly understand how storage is used on their drives. The program represents files, folders, and duplicate items as colorful blocks, making it easy to spot large files, heavy folders, repeated copies, and dominant file types.
Unlike traditional file lists, FileBricks provides several dedicated views for disk analysis. Users can inspect files inside folders, view all files sorted by size, compare folders visually, and review duplicate files in grouped form. Files with the same extension are displayed in the same color, so common categories such as videos, images, archives, executables, and documents can be recognized immediately on the graph.
FileBricks can scan all drives or a selected custom folder. It also includes practical filtering options, allowing users to exclude files by modified date, minimum file size, or filename pattern.

Filect
Filect is an AI file search and organization app for Windows and Mac that helps users find and organize files with natural language. Instead of guessing filenames, digging through folders, or manually cleaning messy drives, users can describe what they are looking for in plain English, and Filect returns matching files based on meaning, content, and context. It reads the content of local files on a hard drive, including PDFs, Word documents, spreadsheets, code files, and images with text, then creates a semantic index so files can be found regardless of their filename or folder location. Filect is built for local file chaos: thousands of downloads, documents, scans, invoices, project files, and PDFs that are already sitting on a computer but are hard to locate later. It can automatically categorize files by content topic, apply AI-generated tags, and organize existing folders into cleaner structures without forcing users to save files into a new system.
