1. Core Library Agnostic - diskdisk-core doesn't depend on any UI framework
2. Safety First - All deletions require explicit confirmation
3. Extensibility - Easy to add new cache types via CacheType and CacheLocation
4. Cross-platform Potential - Currently focused on Windows, but architecture considers future cross-platform support

Contributions are welcome! Please feel free to submit a Pull Request.

1. Add new variant to CacheType enum in crates/core/src/cache_types.rs
2. Add cache location configuration in crates/core/src/scanner.rs
3. Update parse_cache_type() in desktop-gui/src/lib.rs (for GUI)
4. Test with cargo run --bin diskdisk -- --scan

Example:

// cache_types.rs
pub enum CacheType {
    // ... existing types
    MyAppCache,
}

// scanner.rs
CacheLocation {
    cache_type: CacheType::MyAppCache,
    paths: vec![r"%LOCALAPPDATA%\MyApp\Cache".to_string()],
    description: "My Application Cache",
    dangerous: false,
}
