- **Resource Management**: AutoCloseable patterns for file handles and connections
- **Thread Safety**: Components support concurrent access
- **DFS Support**: Distributed File System resolution
- **Streaming Operations**: Efficient directory listings and file operations
- **Buffer Caching**: Optimized buffer management
- **DCE/RPC Protocol**: Support for advanced operations

## Quick Start

### Basic Usage

```java
import jcifs.CIFSContext;

 * to interact with SMB resources.
 *
 * <p>
 * This client supports authentication, content retrieval, and metadata extraction from SMB files.
 * It handles file access, directory listing, and access control entries (ACEs) processing.
 * </p>
 *
 * <p>
 * The class provides methods to:
 * </p>
 * <ul>
 *   <li>Initialize the client with SMB authentication details.</li>
