“She and her lawyers had those emails deleted. And they didn't just push the delete button; they had them deleted where even God can't read them. They were using something called BleachBit. You don't use BleachBit for yoga emails or bridesmaids emails. When you're using BleachBit, it is something you really do not want the world to see.”
Two of the main features that are listed on the BleachBit website include “Shred files to hide their contents and prevent data recovery”, and “Overwrite free disk space to hide previously deleted files”. These two features would make it pretty difficult for anyone trying to recover the deleted emails.
