Ok don't shoot me down if this is a noob question but why does eraser have to erase free space with zillions of 0kb files ? I used to use Window Washer's free space cleaner and it left no files behind. With Eraser, you get hundreds of thousands of randomly named 0kb files after the free space erase. This can cause such a headache if you were to try recovering a file you deleted through normal deletion. Sure Recuva skips those random files and don't spend hours on trying to list them but other recovery software out there like RecoverMyFiles spends quite a long time trying to list those 0kb random files. Why doesn't Eraser erase the freespace thru sector-by-sector overwriting vs. filling the drive with so many 0kb files ?
