Resize VMware Virtual Disk (VMDK) Partition for Windows Guest

As soon as your VMware virtual disk (VMDK) is not having enough disk space, you will have two solutions to increase the disk space on your virtual machines: add another virtual disk on your virtual machine or resize current virtual disk to get much bigger. In most cases, it's easy to have a second virtual hard drive. On the other hand, some people prefer to grow the size of their existing virtual disk in order that they don't need to adjust application or data locations.
