Getting a list of logical drives.

Question

How can I get the list of logial drives (C#) on a system as well as their capacity and free space?

Answer 1

System.IO.DriveInfo.GetDrives()

Answer 2

You can retrieve this information with Windows Management Instrumentation (WMI)

 using System.Management;

    ManagementObjectSearcher mosDisks = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");
    // Loop through each object (disk) retrieved by WMI
    foreach (ManagementObject moDisk in mosDisks.Get())
    {
        // Add the HDD to the list (use the Model field as the item's caption)
        Console.WriteLine(moDisk["Model"].ToString());
    }

Theres more info here about the attribute you can poll

Answer 3

Directory.GetLogicalDrives

Their example has more robust, but here's the crux of it

            string[] drives = System.IO.Directory.GetLogicalDrives();

            foreach (string str in drives) 
            {
                System.Console.WriteLine(str);
            }

You could also P/Invoke and call the win32 function (or use it if you're in unmanaged code).

That only gets a list of the drives however, for information about each one, you would want to use GetDrives as Chris Ballance demonstrates.

Answer 4

DriveInfo[] drives = DriveInfo.GetDrives();

foreach (DriveInfo drive in drives)
{
double fspc = 0.0;
double tspc = 0.0;
double percent = 0.0;

fspc = drive.TotalFreeSpace;
tspc = drive.TotalSize;
percent = (fspc / tspc)*100;
float num = (float)percent;

Console.WriteLine("Drive:{0} With {1} % free", drive.Name,num);
Console.WriteLine("Space Reamining:{0}", drive.AvailableFreeSpace);
Console.WriteLine("Percent Free Space:{0}",percent);
Console.WriteLine("Space used:{0}", drive.TotalSize);
Console.WriteLine("Type: {0}", drive.DriveType);
}
