Message: From a performance point of view - the only maintenance that you need
to do is the make sure that the host file system is not heavily fragmented.
From a size point of view - you would need to periodically:
- Defrag the guest
- Zero out the space
- Compact the drive
Alternatively you could reimage the disk to a new virtual hard disk
periodically.

that zeros out unused space. is this utility compatible with Virtual PC and
vhd's in that environment?
