C# FAQs Series: How To Detect All Drives Connected?

àIn C# FAQs Series: We discuss most frequent questions asked on C# forums.
If you want to know about how many drives are connected to your computer. It’s very easy to detect using C#. Following is simple code…
Source Code:
using System;
using System.IO;
class MyProgram
public static void Main()
DriveInfo[] allDrives = DriveInfo.GetDrives();
foreach (DriveInfo d in allDrives)
Console.WriteLine("Drive {0}", d.Name);
Console.WriteLine(" File type: {0}", d.DriveType);
if (d.IsReady == true)
Console.WriteLine(" Volume label: {0}", d.VolumeLabel);
Console.WriteLine(" File system: {0}", d.DriveFormat);
" Available space to current user:{0, 15} bytes",
" Total available space: {0, 15} bytes",
" Total size of drive: {0, 15} bytes ",
This code produces output similar to the following:
Drive A:\
File type: Removable
Drive C:\
File type: Fixed
Volume label:
File system: FAT32
Available space to current user: 4770430976 bytes
Total available space: 4770430976 bytes
Total size of drive: 10731683840 bytes
Drive D:\
File type: Fixed
Volume label:
File system: NTFS
Available space to current user: 15114977280 bytes
Total available space: 15114977280 bytes
Total size of drive: 25958948864 bytes
Drive E:\
File type: CDRom
The actual output of this code will vary based on machine and the permissions
granted to the user executing it.
