A Visual Studio Code extension that adds line and token count decorations to your file explorer, helping you quickly identify large files that might need refactoring.
- 📊 Visual line and token count indicators
- 🎨 Multiple indicator styles (circles, emojis, icons)
- 🔧 Customizable thresholds and file extensions
- ⚙️ Configurable counting modes (lines or tokens)
- 🚀 Quick preset selection
- 📈 Status bar integration
- ⚡ High-performance parallel processing
- Install the extension from the VS Code Marketplace
- Open your project
- See file size indicators in the explorer view
Choose between:
- Lines count
- Tokens count (useful for LLM context window estimation)
Line Count Explorer now supports customizable presets to quickly switch between different configurations:
Built-in presets:
- Default: General purpose line count thresholds
- LLM Context: Token-based thresholds matching common LLM context window sizes
- Code Review: Metrics tailored for code review complexity
- Documentation: Specialized for documentation file sizes
Custom presets:
- Create your own presets with your preferred settings
- Save current configuration as a preset
- Import and export presets as JSON files
- Manage presets through the command palette
Easily define your own threshold levels using comma-separated values:
0, 100, 500, 1000, 2000, 5000, 10000
Presets automatically use the selected indicator symbol set, or you can choose a different set for each preset.

The v2.0.0 release includes significant performance improvements:
- Parallel Processing: Files are processed in batches to maximize throughput
- Prioritized Indexing: Open files and visible files are processed first
- Asynchronous I/O: Non-blocking file operations for better responsiveness
- Smart Caching: More efficient memory usage in large workspaces
- Cancelable Operations: Stop long-running operations at any time
- Progress Reporting: Visual feedback during indexing operations
- Memory Management: Ability to clear caches and reduce memory footprint
- Optimized Algorithms: More efficient line and token counting
- Event-Based Architecture: Reduced polling for better performance
- Workspace Exclusions: Common directories like node_modules are automatically ignored
These enhancements result in:
- Up to 5x faster indexing for large workspaces
- Significantly reduced memory consumption
- Improved UI responsiveness during operations
- Better handling of very large files and projects
