问题是，我关闭了unity编辑器，而它正在将文件传输到我的设备（安卓三星S9）。 这在设备上留下了一组临时文件，我无法删除，因为我不知道如何访问它们。 这些临时文件在unity编辑器中导致以下错误。
IOException: Failed to Copy File / Directory from 'C:/Program Files/Unity/Hub/Editor/2019.3.13f1/Editor/Data/PlaybackEngines/AndroidPlayer\Data\unity default resources' to 'Temp/StagingArea/Data\unity default resources': destination path already exists.

我如何删除这些临时文件，以便我可以用unity使用我的设备？
原来，临时文件夹是在项目文件夹内，而不是设备上。 通过重启unity，我成功地让它编译并安装在手机上。
