<p>I have a VmWare virtual machine that is coming dangerously close to it's primarry HDD's limit and I need to extend it. How do I do this? I'm working with VmWare Workstation 6.0.5</p>

This link
gives two approaches that should help.
It looks like this is the most straightforward method:
```
```
vmware-vdiskmanager -x 12GB path\to\disk.vmdk
```
```
where 12GB is the desired size of the expanded volume.
