how to find if a drive is a cd-rom drive or floppy?

Question

Hi Right now I am making a program that involves a treeview. The treeview displays a different icon depending the type of the drive. Does anyone know what class I should use to find whether the drive is a hard drive a cd-rom drive or a floppy drive? Thanks in advance

I found WMI is really slow when it comes to retrieving drives. faster way i have done this in the past is to use Environment.GetLogicalDrives(); to retrieve the drive letters. and then use these letters with FileSystemObject to determine the types of drive. WMI way is better but slower.

If you don't find anything easier (lighter) try using WMI: ManagementClass disks = new ManagementClass(Win32_LogicalDisk); ManagementObjectCollection moc = disks.GetInstances(); foreach(ManagementObject mo in moc) { Console.WriteLine(Drive	{0}	Type = {1} mo[Name] mo[DriveType]); mo.Dispose(); } disks.Dispose(); (These class are in System.Management namespace) Disktypes: Unknown = 0; NoRoot = 1; Removable = 2; LocalDisk = 3; Network = 4; CD = 5; RAMDrive = 6;
