MetaFinder

"Find Any File, Filter by Everything"

A powerful metadata extraction and filtering system for Windows that lets you find files instantly by filtering on extracted metadata, not just filename.

🎯 What is MetaFinder?

Think iTunes for all file types. MetaFinder scans your folders once, extracts 90+ metadata fields from every file, and lets you filter/search with a beautiful, fast interface.

The Problem:

• Windows Search only indexes filenames and basic properties
• Finding files requires remembering exact names or locations
• Rich metadata (camera info, GPS, author, BPM, etc.) is hidden and unusable

The Solution:

Scan once → Extract everything → Filter instantly

✨ Features

🚀 One-Time Scan

• Scan 60,000 files in 5-10 minutes
• Never wait again - all queries are instant
• Incremental rescan for changed files

🔍 Rich Metadata Extraction (90+ Fields)

• Images: Camera make/model, GPS location, ISO, aperture, date taken
• Documents: Author, page count, word count, company, keywords
• Audio: Artist, album, BPM, bitrate, duration, lyrics
• Video: Codec, resolution, FPS, duration, audio tracks
• Executables: Version info, company, digital signature
• Archives: Compression method, file count, encryption status
• Source Code: Language, line count, function count, complexity

🎨 Beautiful Filter Interface

• Real-Time Filtering: Results update as you type
• Multi-Criteria Search: Combine any filters (AND/OR logic)
• Saved Queries: Save frequently used filter combinations
• Export Results: CSV, JSON, file lists

⚡ Lightning Fast

• Filter results appear in <100ms
• SQLite database with full-text search (FTS5)
• Optimized indexes for common queries

🎯 Example Searches

Find files you never could before:

📸 "All photos taken with Canon 5D in Paris during 2024"
   Filter: Type=Image, Camera=Canon, GPS=Paris, Year=2024

📄 "PDFs authored by John Smith over 50 pages"
   Filter: Type=PDF, Author=John Smith, Pages>50

🎵 "Running playlist: 140-160 BPM songs"
   Filter: Type=Audio, BPM=140-160

🎬 "4K videos longer than 10 minutes"
   Filter: Type=Video, Resolution>=3840x2160, Duration>600s

📐 "CAD drawings for Building-A project modified this week"
   Filter: Extension=dwg, Project=Building-A, Modified=Last7Days

🚀 Quick Start

Status: Working Prototype Available! ✅

We have a fully functional prototype with:

• ✅ CLI interface (scan, search, stats)
• ✅ GUI interface (modern CustomTkinter design)
• ✅ PyExifTool integration (1000+ file formats)
• ✅ SQLite database with fast queries
• ✅ All tests passing

Installation

# 1. Clone the repository (ExifTool included!)
git clone https://github.com/yourusername/MetaFinder.git
cd MetaFinder

# 2. Install Python dependencies
pip install -r requirements.txt

# 3. Run!
python metafinder_gui.py

That's it! ExifTool is now pre-bundled in the repository:

• ✅ Windows: ExifTool 13.45 included in vendor/bin/ (~34 MB)
• ✅ No downloads needed - clone and run
• ✅ No PATH setup - works immediately
• ✅ Portable - move folder anywhere

macOS/Linux users:

# ExifTool not pre-bundled for your OS - install once:
# macOS:
brew install exiftool

# Linux:
sudo apt install libimage-exiftool-perl

# Then run MetaFinder normally

Run GUI (Recommended)

python3 metafinder_gui.py

Run CLI

# Scan a folder
python3 metafinder_cli.py scan ~/Pictures

# Search for files
python3 metafinder_cli.py search --type image --camera Canon

# View statistics
python3 metafinder_cli.py stats

# Get file info
python3 metafinder_cli.py info ~/Pictures/photo.jpg

📖 How to Use

1. Initial Scan

• Click "Scan Folder"
• Select your top-level directory
• Wait for scan to complete (5-10 mins for 60k files)
• Database created with all metadata

2. Filter & Search

• Select filters from left sidebar
• Results update in real-time
• Combine any filters (AND logic by default)
• Use quick search for keywords

3. Work with Results

• Double-click to open file
• Right-click for context menu
• Select multiple files for batch actions
• Export results to CSV/JSON

4. Save Queries

• Click "Save Query" to save current filters
• Give it a name (e.g., "My Running Playlist")
• Load saved queries anytime

5. Incremental Rescan

• Click "Rescan" to update changed files
• Much faster than full scan
• Only processes new/modified files

🏗️ Architecture

Components:

1. Scanner Engine: Extracts metadata using specialized extractors
2. Database Layer: SQLite with FTS5 for fast queries
3. Filter UI: CustomTkinter-based modern interface

Metadata Extractors:
