How not to advertise your product

"When Defraggler reads or writes a file, it uses the exact same techniques that Windows uses. Using Defraggler is just as safe for your files as using Windows." -- source

I was just updating the CCleaner program I use, and thought I would take a look at the other programs they've posted on the new site. When I saw what I've just quoted above, on their defrag tools features page... I could not help but think "THAT IS THE WORST DAMN PITCH EVER!", as safe for your files as using Windows!? Seriously folks!
