如何识别某盘符的类型，是硬盘、软盘、光盘、还是USB盘，最主要是如何实别出是否为USB盘

[Ah]

好像没办法识别出来。
在windows中，USB和硬盘一样对待。

GetDriveType
The GetDriveType function determines whether a disk drive is a removable, fixed, CD-ROM, RAM disk, or network drive.

UINT GetDriveType(
LPCTSTR lpRootPathName // root directory
);
Parameters
lpRootPathName
[in] Pointer to a null-terminated string that specifies the root directory of the disk to return information about. A trailing backslash is required. If lpRootPathName is NULL, the function uses the root of the current directory.
Return Values
The return value specifies the type of drive. It can be one of the following values.

Value Meaning
DRIVE_UNKNOWN The drive type cannot be determined.
DRIVE_NO_ROOT_DIR The root path is invalid. For example, no volume is mounted at the path.
DRIVE_REMOVABLE The disk can be removed from the drive.
DRIVE_FIXED The disk cannot be removed from the drive.
DRIVE_REMOTE The drive is a remote (network) drive.
DRIVE_CDROM The drive is a CD-ROM drive.
DRIVE_RAMDISK The drive is a RAM disk.

同意楼上，用GetDriveType
我估计USB识别出来应该是
DRIVE_REMOVABLE

测试看看结果？

GetDriveType不行吧，软盘和USB都是DRIVE_REMOVABLE。

我用的还是vc 6.0

查msdn得到的

HRESULT GetDeviceInfo(
LPDIDEVICEINSTANCE pdidi
);

参数和返回值都和你说得不一样呀
你确定 GetDeviceInfo 是如你所说的吗？

[cocosky]

系统 xp , 开发工具 vc 6.0 ， 函数 GetDriveType

测试结果 usb 移动硬盘 DRIVE_FIXED(同其他硬盘一样)
usb u 盘 DRIVE_REMOVABLE(同软盘一样)

[Linux2001]

就用GetDriveType可以了啊

如果你的电脑有光驱，那好办光盘后的都为USB盘
