How to get all drives in PC with .NET using C#

Question

how to get all drives in a PC. and types of every drive and free-space of each

i.e. System-Drive, CD-Drive, DVD-Drive, Removable, ... etc.

If a system is attached with a new drive may be a pen drive or external hard disc.

How to detect them at time of attachment ?

To get a list of the drives, you can use the System.IO.DriveInfo class:

foreach(var drive in DriveInfo.GetDrives())
{
    Console.WriteLine("Drive Type: {0}", drive.DriveType);
    Console.WriteLine("Drive Size: {0}", drive.TotalSize);
    Console.WriteLine("Drive Free Space: {0}", drive.TotalFreeSpace);
}

Unfortunately, this doesn't provide a way to listen for USB Key Insertions. There is another question dealing with that you could check out:

                "\t\t" + drive.DriveType.ToString();

                s = s + "\n\r";
            }
        }
        return s;
    }

Just mentioning: you can actually include a picture in your post by just uploading it (click on the `insert picture` icon. This way it can appear inline instead of requiring to follow your link. — Qortex, Mar 08 '13 at 21:46

You can get the drives and info quite easily

DriveInfo[] drives = DriveInfo.GetDrives();

foreach (DriveInfo drive in drives) 
{
    Console.WriteLine(drive.Name);
    Console.WriteLine(drive.TotalSize);
}

There's a good article on detecting adding/removing drives on CodeProject

The WMI libraries will probably help. Also there's a codeproject article that talks about this:

Here is the answer to your first question. To get all logical drives you can try this:

string[] drives = Environment.GetLogicalDrives();

The System.IO.DriveInfo class is the place to start. The DriveType property can tell you what you are looking for.

To get all the drives currently attached:

DriveInfo[] allDrives = DriveInfo.GetDrives();

And for the detection you have to listen to WMI events. Check this out: http://www.techtalkz.com/c-c-sharp/182048-need-detect-insertion-removal-usb-drive.html
