I am trying to Securely delete files and have followed the posted directions. No. 3 of the directions in "Securely deleting your files", it says Right click the list and click SECURE DELETE CHECKED. When I right click only SECURE OVERWRITE HIGHLIGHT or SECURE OVERWRITE CHECKED is listed, not "DELETE CHECKED". Where is that option, as that is what I want to do. Secondly, After running Recuva, I am wondering if you can delete numerous files, rather than one at a time. If so, how?
