## What it is
dupeGuru is a cross-platform GUI application for finding duplicate files on Linux, macOS, and Windows, written mostly in Python 3 with a Qt-based interface. It scans filenames or file contents with fuzzy matching, and offers special Music and Picture modes for tag-based and image-similarity deduplication.

## Use cases
- find duplicate files on my computer
- deduplicate photos that look similar
- remove duplicate music files by tags
- fuzzy match similar filenames
- free up disk space by deleting duplicates
- compare file contents to spot duplicates

## When to choose
- you want a polished GUI rather than a command-line dedupe script
- you need fuzzy filename matching or similar-picture detection, not just exact hashes
- you work across Linux, macOS, and Windows and want one tool
- you want safety features like reference directories and grouping to avoid accidental deletes

## When to avoid
- you need a headless or scriptable deduplication pipeline for servers
- you require active maintenance on macOS packaging or translations, which the project is seeking help with
- you need deduplication integrated into a backup or storage system rather than a standalone desktop app

## Facets
- artifact type: application

- function: gui, search-engine, file-system, developer-tools
