实现类似Windows文件管理器的文件夹选择界面

创建了一个完整仿Windows资源管理器的界面:

1. 界面布局:
   - 顶部:路径工具栏(路径输入框 + 浏览按钮)
   - 左侧:文件夹树形视图(显示所有驱动器和文件夹结构)
   - 右侧:文件列表视图(详细列表,包含名称、日期、类型、大小)
   - 底部:状态栏(显示文件夹和文件统计信息)

2. 功能特性:
   - 树形文件夹结构导航
   - 实时文件列表显示
   - 支持键盘操作(回车确认路径)
   - 双击文件夹快速导航
   - 动态加载子文件夹(按需加载提高性能)
   - 文件类型识别和大小格式化
   - 详细的状态信息显示

3. 用户体验:
   - 更大的界面尺寸(800x600)
   - 类似Windows资源管理器的操作习惯
   - 左右分栏设计,信息展示更清晰
   - 支持多种导航方式(树形、列表、路径输入)

4. 性能优化:
   - 懒加载子文件夹,避免初始加载过慢
   - 异步处理UI更新
   - 错误处理和权限检查

现在的文件夹选择界面更加专业,完全模拟了Windows文件管理器的体验!
