Defragmenting with vmware-vdiskmanager utility

HI

Using vmware-vdiskmanager utility of Workstation 8.0.1 to defragment the virtual disks of virtual machines without snapshots, I would write:

For the Flat virtual disks:

"C:\Program Files (x86)\VMware\VMware Workstation\vmware-vdiskmanager.exe" -d "<FlatVirtualDiskDescriptiveFile>.vmdk"

For the Sparse virtual disks:

"C:\Program Files (x86)\VMware\VMware Workstation\vmware-vdiskmanager.exe" -d "<SparseVirtualDisk>.vmdk"

Right?

THANKS

BYE
