Resize VMWare Disk size VMWare provides an option to resize the Hard disk of a VM. The Settings dialog provides this option under Hard Disk. If the VM is not running and you don’t have a snapshot, the slider is enabled, and you can size the disk to your desired size. I wanted to increase the size of the hard disk from 50 GB to 100 GB. That’s a matter of seconds, and I was ready to go.
