Calling Windows Hard Disk Defragmenter

[sonia.sardana]

Can somebody tell me how to call Windows Hard Disk Defragmenter in VB.Net
on Button Click. Any help is greatly appreciated.

Defrag Method of the Win32_Volume Class (Windows)

WMI Tasks: Disks and File Systems (Windows)

Script example from the 2nd link. Should be able to convert this to .NET pretty easily.

strComputer = "."
Set objWMIService = GetObject("winmgmts:\\" _
    & strComputer & "\root\cimv2")
Set colVolumes = objWMIService.ExecQuery _
    ("Select * from Win32_Volume Where Name = 'K:\\'")
For Each objVolume in colVolumes
     errResult = objVolume.Defrag()
Next
