推荐答案

这通常意味着，要么有一个文件夹命名为G：\歌，所以你不能替换目录一个文件，或者您的Windows用户帐户不具备的许可以写入到该驱动器。

This usually means that either there is a folder named "G:\Song", so you can't replace a directory with a file, or that your windows user account doesn't have permission to write to that drive.

在驱动器上单击鼠标右键，并期待在安全权限，以确保您有权限。此外，还要确保该驱动器不是只读的，作为一个写保护SD卡或闪存驱动器的情况下。

Right-click on the drive and look at security permissions to be sure you have permission. Also, make sure the drive is not readonly, as in the case of a write-protected SD card or flash drive.
