如何使用 Delphi 在 Windows 中从 USB 驱动器挂载分区？

how to mount partitions from USB drives in Windows using Delphi?

我想在 Windows (XP) 中从 USB 驱动器挂载所有分区。我的意思是我想为他们每个人分配驱动器号(当他们没有驱动器号时)。
操作系统会自动执行此操作，但在某些情况下此类程序很有用。

我知道如何确定驱动器是否在 USB 上。
到目前为止，我的代码是：

end;
finally
CloseHandle(H);
end;
end;

end.

但我不知道如何访问每个驱动器上的分区并安装它们。
你能帮帮我吗？

看看卷管理功能 – http://msdn.microsoft.com/en-us/library/aa365730(v=vs.85).aspx

FirstFirstVolume、FindNextVolume、FindVolumeClose 会将分区列为 \\\\\\\\\\\\\\\\?\\\\\\\\Volume{Guid} 名称。

Createfile 应该能够选择卷名，以便您上面的代码可以检查它的 USB。

SetVolumeMountPoint 允许您将卷安装为驱动器号或文件夹安装点。

这篇博文讨论了卷名 – http://blogs.msdn.com/b/adioltean/archive/2005/04/16/408947.aspx
