delete

I want to minimize the amount of space my virtual disk is using, by zero'ing out the data on any deleted files. The virtual disk is a VDMK running ubuntu on VirtualBox.

What is the best way to find any deleted files, and zero them out, so that when I export the appliance the disk size is only existing files on the disk?
