Sometimes you create a VMware image and later realize that you should have made the drive size larger. Fortunately in VMWare Workstation you can change the size of a disk with a simple command line program. But the command only makes your drive bigger not the actual partition the operating system resides on. It is possible to get around this problem without purchasing a product like Partition Magic. There is a free program from the OpenSource and Linux world called “QTParted”. So the first thing you need to do is resize the drive by issuing the VMware command line to resize the disk (in this case to 10Gb):

vmware-vdiskmanager -x 10GB myDisk.vmdk

Then you set the VMware session to boot off a Knoppix ISO CD image. Then run QTParted. Select the Windows Drive partition with the right mouse button and chose reseize, set the new size, and then commit the change. Your disk’s OS partition has now been increased with all data intact.
