System占用进程导致U盘无法弹出

我已看到你的问题：
您可以检查一下u盘是否有文件没有保存关闭。
如果有应用程序在u盘中运行，请把该应用程序退出
如果还有，可以请解除占用的软件来解除
如果以下方法已试过（后台没有运行u盘里的文件），可以直接拔出。

I have seen your question:

You can check if there are any files in the USB drive that haven't been saved and closed.

If there is an application running on the USB drive, please exit the application

If there is still one, you can ask to release the occupied software to release it if the following methods have been tried (no files from the USB drive are running in the background), you can directly pull out.
