Dell ExtPart.exe; Extend Volumes Easily.

This is a great little tool if you wanna extend the OS drive of a VM. Go into vShere and give your VM's OS HD an extra few gigs.

BTW - you can do this HOT. So, if you're going from a 20GB drive to a 40GB drive, then you will run this little exe from the VM itself. Opens a CMD window.

Volume to Extend, type C:
Size to expand the volume, type  20480

now go check your HD size in Windows Explorer :)
