推荐答案

您正在访问MyDocuments文件夹，这是一个SpecialFolder。您无法在正常模式下访问该文件夹，只有具有提升权限的受信任应用程序才能访问此类特殊文件夹。



请检查您的权限，然后重试。如果是其他任何东西，我就超出了我的深度：）

You are accessing the MyDocuments folder, which is a SpecialFolder. You cannot access the folder in normal mode, only trusted applications with elevated privilege can access such type of special folder.

Please check your permissions and try again. If it is anything else, I'm out of my depth :)
