Think of deleting a file, as tearing the Table of Contents out of a book.
How to navigate through the book is missing, but the contents of the book is still there.
Shredding makes a selected number of passes, back and forth over the file, with 1's and 0's.
The same as passing a book through a shredder, over and over.
The more passes, the less the chance of reconstructing the book (file)
Spybot has a shredder feature.
Tools / Secure Shredder
Drag the file into the open box.
At the bottom, select the number of shreds.
Click the Chop it away!
Use 4 shreds or more, to be sure the file isn't able to be recovered, without the use of some expensive software.
You can also use third-party software, which is what I do.
I use Eraser
It adds an entry to the context menu (right-click menu)
, which, for me, is easier to use.
Just right-click the file, and select Erase
It can also be set, to the number of shredding passes you want to use.
