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

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\t{0}\tType = {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;
