REcuva recovers files after wiping wicht ccleaner and secure eraser.

Hi, i wantet to clean my harddrive so i used secure eraser more than 2 times and the ccleaner (both the cleaner and the drive wiper)but when i used the recuva deep scan many of those files show up again. How can i get rifd of files for sure? Especially since many of them are in a Folder called "?" and i cant find that folder if it exists
