#### 4.2 Implementation Tasks
- [ ] Extend lease implementation for directories
- [ ] Implement directory metadata caching
- [ ] Add directory change notification integration
- [ ] Create parent-child lease relationships
- [ ] Implement directory lease break handling
- [ ] Add directory enumeration caching

#### 4.3 Integration Points
- Extend `SmbFile` for directory lease support

## 12. Future Enhancements

1. **Directory Leases**: Extend lease support for directories
2. **Lease Key Persistence**: Save lease keys for reconnection
3. **Parent-Child Relationships**: Implement hierarchical leases
4. **Lease Sharing**: Support lease sharing across handles

     * a file or directory. See the description and examples of smb URLs above.
     *
     * @param   url A URL string
     * @throws  MalformedURLException
     *          If the <code>parent</code> and <code>child</code> parameters
     *          do not follow the prescribed syntax
