TrID UI

English • Deutsch • Español • Français • Italiano • 日本語 • Polski • Português • Русский • 简体中文

TrID UI is a lightweight desktop application that provides a user-friendly interface for TrID, a powerful tool for scanning and analyzing files. With TrID UI, users can easily select or drop files on the Home screen to initiate local scans, making it convenient to detect unrecognized filetypes.

The application uses a native Go implementation of the TrID file identification algorithm, providing fast and accurate file type detection without external dependencies.

Prerequisites

The application can automatically download and update the TrID definitions file for you!

Option 1: Automatic Download (Recommended)

1. Launch TrID UI
2. Go to Settings
3. Click "Download Definitions" or "Check for Updates"
4. The app will automatically download and install the latest definitions

Option 2: Manual Installation

1. Download the TrID definitions file (triddefs.trd) from Mark0.net
2. Place the triddefs.trd file in your application data directory:
   • Windows: %APPDATA%\TridUI\triddefs.trd
   • macOS: ~/Library/Application Support/TridUI/triddefs.trd
   • Linux: ~/.local/share/TridUI/triddefs.trd

You can use the "Open App Dir" button in Settings to navigate to the correct location.

Building from Source

📖 Full build documentation: See build/README.md for detailed instructions and troubleshooting.

Quick Build:

# Windows
.\build\build-windows.bat

# macOS
chmod +x build/build-darwin.sh && ./build/build-darwin.sh

# Linux
chmod +x build/build-linux.sh && ./build/build-linux.sh

What the build scripts do:

• ✅ Validate prerequisites (Go 1.22+, Wails CLI, Node.js, pnpm)
• ✅ Check system dependencies
• ✅ Detect optional tools (UPX, NSIS, create-dmg)
• ✅ Auto-detect architecture
• ✅ Create distributable packages

Minimum Requirements:

• Go 1.22+ • Node.js 20+ • pnpm 10+ • Wails CLI

Install Wails CLI:

go install github.com/wailsapp/wails/v2/cmd/wails@latest

Output locations:

• Windows: build/bin/windows/TridUI-win-{arch}.exe
• macOS: build/bin/darwin/TridUI-macOS-{arch}.dmg (+ .app, .zip)
• Linux: build/bin/linux/TridUI-linux-{arch}

Usage

1. Launch TrID UI
2. Click or drag-and-drop a file onto the interface
3. View the scan results with confidence scores
4. The best match is highlighted at the top
5. Additional possible matches are listed below

Technical Details

Architecture

• Backend: Go (Wails framework)
• Frontend: SvelteKit + TypeScript + DaisyUI (& Tailwind CSS)
• TrID Engine: Pure Go implementation (/trid package)

TrID Scanner Implementation

The TrID scanner (/trid/trid.go) is a clean-room Go implementation that:

• Parses TRD (TrID Definition) files using the binary format specification
• Performs pattern matching at specified file offsets
• Supports string matching for enhanced accuracy
• Calculates confidence scores based on pattern weights
• Returns ranked results with detailed file type information

You can find the TRD format specification on Mark0.net.
