How to Increase VMWare Hard Disk Size?

I've been playing with virtual machines and testing some odd things that can not be easily tested on a real computer, suddenly I come across to a situation that my virtual machine's hard disk size needed to be increased.

It is one simple command! You just need to go where you installed VMWare WorkStation, there is a file named: vmware-vdiskmanager.exe

You just need to open a command window and run:

vmware-vdiskmanager.exe -x sizeGB virtualDiskFile.vmdk

That's all.
