npx cap sync
```

## 🚀 快速开始

### 基础使用

```typescript
import { AdvancedFileManager } from 'capacitor-advanced-file-manager';

// 列出目录内容
const files = await AdvancedFileManager.listDirectory({
  path: '/storage/emulated/0',
  showHidden: false
});

// 创建文件
await AdvancedFileManager.createFile({
  path: '/storage/emulated/0/test.txt',
  content: 'Hello World!'
});
```

### 模块化使用

```typescript
// 按需导入高级功能模块
import { FileSearch } from 'capacitor-advanced-file-manager/search';
import { BatchOperations } from 'capacitor-advanced-file-manager/batch';
import { WebEnhancedFileManager } from 'capacitor-advanced-file-manager/web-enhanced';

// 文件搜索
const results = await FileSearch.search({
  directory: '/storage/emulated/0',
  query: '*.jpg',
  recursive: true
});

// 批量操作
await BatchOperations.batchDelete([
  '/path/to/file1.txt',
  '/path/to/file2.txt'
]);

// Web端增强功能 - 突破浏览器文件限制
await WebEnhancedFileManager.initializeWebFS({
  useOPFS: true,              // 使用 Origin Private File System
  enableIndexedDBCache: true, // 启用 IndexedDB 缓存
  useWebWorkers: true         // 使用 Web Workers 处理大文件
});
```
