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！ 🤖 Generated with [Claude Code](https://claude.com/claude.code) Co-Authored-By: Claude <noreply@anthropic.com>
