How to get Available Disk Space in VB.Net

With the help of DriveInfo class and GetDrives static property of DriveInfo class,we can achieve.

GetDrives is used to retrieves the drive names of all logical drives.
DriveInfo class comes inside System.IO Namespace.

Dim drive_info() As IO.DriveInfo = IO.DriveInfo.GetDrives
   For Each Drv In drive_info
       If Drv.IsReady Then
          MsgBox(Drv.Name & " " & Drv.AvailableFreeSpace.ToString)
   End If
Next

The IsReady property returns true if the drive is ready otherwise returns false if the drive is not ready.

AvailableFreeSpace property indicates the amount of free space in all the Drives i.e. C:\,D:\ and so on.
