一、通过调用GetDriveType API函数来完成

　　下面的代码就可以检索出系统中所有的驱动器：

　　表单的ACTIVATE方法：

        Declare Long GetDriveType In "kernel32" String nDrive

        Dime I, DrvName, DrvType
        For I = 0 To 25
            DrvName = Chr(I + 65) + ":"
            DrvType = GetDriveType(DrvName)
            Do Case
                Case DrvType =  2
                    Print "驱动器" + DrvName + "是一个软盘驱动器"
                Case DrvType = 3
                    Print "驱动器" + DrvName + "是一个硬盘驱动器"
                Case DrvType = 4
                    Print "驱动器" + DrvName + "是一个可移去式驱动器或网络驱动器"
                Case DrvType = 5
                    Print "驱动器" + DrvName + "是一个CD-ROM驱动器"
                Case DRIVE_RAMDISK
                    Print "驱动器" + DrvName + "是一个RAM 盘"
                Case Else
            EndcCase
        Next I

　　二、使用FOXTOLLS.FLL中的DriveType函数

　　表单的ACTIVATE方法：

　　Set Libriry To FoxTools.FLL

        Dime I, DrvName, DrvType
        For I = 0 To 25
            DrvName = Chr(I + 65) + ":"
            DrvType = DriveType(DrvName)
            Do Case
                Case DrvType =  2
                    Print "驱动器" + DrvName + "是一个软盘驱动器"
                Case DrvType = 3
                    Print "驱动器" + DrvName + "是一个硬盘驱动器"
                Case DrvType = 4
                    Print "驱动器" + DrvName + "是一个可移去式驱动器或网络驱动器"
                Case DrvType = 5
                    Print "驱动器" + DrvName + "是一个CD-ROM驱动器"
                Case DRIVE_RAMDISK
                    Print "驱动器" + DrvName + "是一个RAM 盘"
                Case Else
            EndcCase
        Next I
