 - 每轮轮询会扫描每行配置的本地目录。
 - 仅同步新增或修改过的文件（避免重复上传同一文件）。
-- 不会删除本地文件。
+- 单个文件上传成功后，会将该文件从本地目录转移至备份目录（源目录名 + `_bak`，例如 `D:\sbFile\DRFID02004` -> `D:\sbFile\DRFID02004_bak`），源目录中对应文件即被移除。
+- 若备份目录中已存在同名文件，会自动在文件名后追加时间戳避免覆盖。
 - Windows 下首次启动 `QMSFileCollector.exe` 时，会自动写入当前用户自启动项（优先写入 `Startup` 启动文件夹，失败时回退注册表 `HKCU\Software\Microsoft\Windows\CurrentVersion\Run`）。
