文件管理器进入多级目录后，过段时间会自动跳转到根目录

1.通过文件管理器进入多级目录后，过段时间会自动恢复到根目录。
第二个问题是上传文件是如果是覆盖，或者删除操作时。可不可以给一个二次确认的弹窗？提示用户是否覆盖或者删除。


No file, test, or entry point is named in the issue. First reproduce the directory reset after entering a multi-level path, then inspect the file-manager navigation and upload/delete flows. Done means the selected directory remains open over time and overwrite/delete actions show a confirmation prompt.
