For those of you who are interested in secure file wiping, but don't use Internet Sweeper, PGP has a feature which sounds similar to IS file wiper. You can either wipe a deleted file with random data, or wipe all your free disk space. I haven't tried it our myself - regular defragging keeps me happy
Bubs, Don't want you feeling more secure than you are. Regular defragging will not remove deleted data unless it has been wiped first. Even a one time wipe and then a defrag will keep you fairly secure as the defrag eliminates the deleted directory structure and file names. But, not until it's wiped! Not deleted, but wiped.
