+## Architecture
+
+The application uses a modular architecture with separate extractors and formatters:
+
+### Extractors
+- **MediaInfoExtractor**: Extracts detailed track information using PyMediaInfo
+- **FilenameExtractor**: Parses metadata from filenames
+- **MetadataExtractor**: Extracts embedded metadata using Mutagen
+- **FileInfoExtractor**: Provides basic file information
+
+### Formatters
+- **MediaFormatter**: Formats extracted data for display
+- **TrackFormatter**: Formats video/audio/subtitle track information
+- **SizeFormatter**: Formats file sizes
+- **DateFormatter**: Formats timestamps
+- **DurationFormatter**: Formats time durations
+- **ResolutionFormatter**: Formats video resolutions
