DriveInfo Class:

Developers and programmers have to handle with the file system in their normal programming practice. Which includes accessing drives, folders, and files for operation. System.IO namespace in .NET Framework provides many classes to work with the file system. One of the classes is DriveInfo class.

Use DriveInfo to determine what drives are available, and what type of drives they are. You can also query to determine the capacity and available free space on the drive. We use this class to get information about computers system. This class provides some methods and properties to Query for drive information.

Following are some Commonly Used Properties of the DriveInfo Class.

Following are some Commonly Used Methods of the DriveInfo Class.

The following code example demonstrates the use of the DriveInfo class to display information about all of the drives on the current system.

/*Example - DriveInfo Class - InfoBrother*/

using System;
using System.IO;

class DriveinfoClass
{
    public static void Main()
    {
        DriveInfo[] allDrives = DriveInfo.GetDrives();

        foreach (DriveInfo d in allDrives)
        {
            Console.WriteLine("Drive {0}", d.Name);
            Console.WriteLine("  Drive type: {0}", d.DriveType);

            if (d.IsReady == true)
            {
                Console.WriteLine("  Volume label: {0}", d.VolumeLabel);
                Console.WriteLine("  File system: {0}", d.DriveFormat);
                Console.WriteLine(
                        "  Available space to current user:{0, 15} bytes",
                           d.AvailableFreeSpace);

                Console.WriteLine(
                       "  Total available space:          {0, 15} bytes",
                          d.TotalFreeSpace);

                Console.WriteLine(
                        "  Total size of drive:            {0, 15} bytes ",
                           d.TotalSize);

                Console.ReadKey();
            }
        }
    }
}

//The result will be something similar to the following.
Drive C:\
  Drive type: Fixed
  Volume label:
  File system: NTFS
  Available space to current user:   142578290688 bytes
  Total available space:             142578290688 bytes
  Total size of drive:               213681958912 bytes
Drive D:\
  Drive type: Fixed
  Volume label:
  File system: NTFS
  Available space to current user:    31930658816 bytes
  Total available space:              31930658816 bytes
  Total size of drive:               107374178304 bytes
Drive E:\
  Drive type: CDRom 
Drive F:\
  Drive type: Removable
