No, he's talking filling with zeros unused blocks. That's a prerequisite to optimize for a sparse image _on the other side_ and/or compression during the transfer.
I know of an ext2/3/4 utility that does precisely that. I have no idea if such an utility exists for NTFS.
It exists for NTFS, have a look at "sdelete.exe" with -c option.
