## Usage
`@push.rocks/smartfile` provides a robust suite of tools for managing files in Node.js projects using modern TypeScript and ESM syntax. It simplifies numerous file operations such as reading, writing, copying, and streaming files, as well as working with directories and virtual file systems.
`@push.rocks/smartfile` offers a comprehensive set of utilities for handling files in Node.js projects using modern TypeScript and ESM syntax. It simplifies various file operations such as reading, writing, copying, and streaming files, as well as working with directories and virtual file systems.
### **Key Features and Classes**
### Key Features and Classes
- **`SmartFile`**: Facilitates reading from and writing to individual files, managing metadata.
- **`StreamFile`**: Optimizes memory usage by enabling efficient file streaming.
- **`VirtualDirectory`**: Allows manipulation of a group of files or directories as a virtual file system.

### **Streaming Large Files**
### Streaming Large Files
For large files, `StreamFile` provides a memory-efficient streaming solution:
```typescript
import { createReadStream } from 'fs';
const sourceStream = createReadStream('./large-video.mp4');
const myStreamFile = await StreamFile.fromStream(sourceStream, 'large-video.mp4');
await myStreamFile.writeToDir('./storage');
console.log('Large file streamed to disk successfully.');
