Bonehead me used bleachbit as root to clean my normal user directory structure and watched it, for some reason I never bothered to follow up, wipe everything back to pristine install state a while back. Sigh... But the interesting thing when attempting to recover my doc, pic, music, etc files is that they were divided into standard size chunks (making music recovery problematic > impossible). If all Hillary's people did was a standard cleaning, that WOULD BE amateur, and the data would be potentially recoverable. Bleachbit CAN do multipass Zero writeovers, but that's not the standard setting. Rr
