推荐答案

您可以使用GetLogicalDrives获取所有可用的驱动器. 在每个可用逻辑驱动器上使用GetDriveType会告诉您它是否是可移动驱动器.

然后，您可以为WM_DEVICECHANGE消息创建处理程序，以便在插入或拔出可移动驱动器时得到通知.
在此处理程序中，您可以重新枚举逻辑驱动器并查找它们是否可移动.

You can get all available drives using GetLogicalDrives.
Using GetDriveType on each of the available logical drives will tell you if it is a removable drive.

Then you can create a handler for the WM_DEVICECHANGE message so that you''re notified whenever a removable drive is plugged or unplugged.
In this handler you could re-enumerate the logical drives and find if they are removable or not.
