I recently needed to expand the main drive that one of my Virtual Machines was using. I didn’t find any built in menu options that allowed this, but I did find that VMWare has an external utility that does this for you.

Information on the Virtual Disk Manager can be found on their website at:

WMWare Virtual Disk Manager

A sample command to expand a virtual disk looks like this:

vmware-vdiskmanager -x 12GB C:PATH_TO_DISKThe_Disk_In_Question.vmdk

This command resized the disk to be 12GB.The new size of the virtual Disk will be 10 GB in this example.

The utility ships with VMWare Workstation, which I use.

Now, be aware, this doesn’t fulfill all your hopes and dreams – at least not mine.  The utility does not preserve snapshots.  You’ll be reduced to one disk image.  If you have a large snapshot tree, like myself, you will only want to expand your drive if you have no other options.
