## Filtering Features

### 🔍 GitIgnore Support
- **Automatic Detection**: Finds and loads .gitignore files from the target directory and parent directories
- **Standard Patterns**: Respects all standard .gitignore syntax including negation patterns (!)
- **Hierarchical Loading**: Loads .gitignore files from current directory up to the analysis root

### 🎯 Custom Glob Patterns
- **Flexible Patterns**: Add your own ignore patterns using glob syntax
- **Common Patterns**: Built-in patterns for .git, node_modules, .DS_Store, etc.
- **Pattern Testing**: Test patterns against specific paths before running analysis

### 📋 Supported Pattern Examples
```
node_modules/          # Ignore node_modules directories
*.log                  # Ignore all .log files
.git/                  # Ignore .git directories
build/                 # Ignore build directories
temp*                  # Ignore anything starting with "temp"
!important.log         # Don't ignore important.log (negation)
```

## Speed Presets

Choose the right speed for your system and needs:

- **🚀 Turbo (Fastest)**: No delays, 500 folder batches - Maximum speed
- **⚡ Fast**: 10ms delays, 200 folder batches - Good for modern SSDs
- **🐢 Normal (Balanced)**: 50ms delays, 100 folder batches - Default, works well everywhere
- **🌱 Gentle (Disk-friendly)**: 100ms delays, 50 folder batches - Good for older HDDs
- **🐌 Ultra Gentle (Very slow, very safe)**: 250ms delays, 25 folder batches - Maximum safety

## Usage Examples

```bash
# Interactive CLI with menu
npx empty-folder-manager

# The tool will guide you through:
# 1. Configure Path: Set the directory you want to analyze
# 2. Configure Speed: Choose your preferred processing speed
# 3. Configure Filters: Set up .gitignore support and custom patterns
# 4. Run Analysis: Scan for empty folders with intelligent filtering
# 5. Show Stats: View analysis results and filtering statistics
# 6. Remove Folders: Choose dry-run or actual removal
# 7. Launch Web UI: Switch to web interface
# 8. Exit: Quit the application
```

### Web UI Interface
```bash
# Launch web UI

```

## Safety Features

- ✅ **Dry-run mode**: Preview what would be removed without making changes
- ✅ **Confirmation prompts**: Multiple confirmations before actual deletion
- ✅ **Error handling**: Graceful handling of permission errors and inaccessible folders

- ✅ **Configurable speed**: Choose from 5 speed presets to match your system
- ✅ **Batch processing**: Processes folders in batches for better performance
- ✅ **Cross-interface consistency**: Same safety features across CLI and Web UI

## Configuration Files

The tool creates configuration files in the directory where you run it:

- `.empty-folders-config.json`: Stores your configured path, speed settings, and filter preferences
- `.analysis/`: Directory containing analysis results
- `analysis-{hash}.json`: Analysis data for each configured path including filtering statistics

## Requirements

- Node.js 14.0.0 or higher
- Read/write permissions for the directories you want to analyze
- For Web UI: Modern web browser (Chrome, Firefox, Safari, Edge)
