Vista - How to zero the deleted data in VPC

Hi there,

I read the document about VPC and it says as following.

When you delete files from a virtual hard disk, the data associated with
these files is usually not removed. Instead, it is marked as available for
use by the operating system; data is not actually deleted until it is
overwritten. You must run a disk utility program to zero the deleted data
before using the compact option.

I tried with CCleaner, TuneUp Utilities and Disk Cleanup but I could not
delete the zero files and it is sitll make my VHD file big even though I
have already many files. Could you please help me on this?

Thanks

That applies to all disks, not just virtual disks - that's how undelete
utilities work...
CCleaner isn't designed to do what you want:

Neither is TuneUp Utilities:

And the built-in Disk Cleanup utility certain isn't:
http://en.wikipedia.org/wiki/Disk_Cleanup

You need a utility which will completely erase deleted files. Microsoft
provide one for you - the Virtual Disk Precompactor. It's delivered as a CD
image, so you need to capture it like any other CD.

However, first you need to defragment the virtual disk that you want to
compact.

Then, navigate to the Virtual Disk Precompactor CD and run the Precompact
utility.

Finally, shut down the VM and run "Virtual Disk Wizard" from the VPC console
to compact the VHD.
