What is File Shredding and Do I Need It?
In simple terms both the Recycle Bin and the delete command only partially, if at all, destroy the file you have chosen to erase.
Enter file shredding. If you want to remove files totally and permanently from your computer, you will need to find a program that rewrites the file with a totally random group of binary data. This is done repeatedly. When the process is done, you have what is commonly called file shredding. It now becomes highly unlikely that the file can be found anymore.
I was quite surprised as I was looking for programs to do this kind of a job to find that my AVG anti-virus (free edition) has a file shredder built into it.
After I clicked Shred it, it informed me that my file was shredded successfully. But was it? I don’t know. I did a search for it and received the following information.
Of course, once the shortcut is deleted, it should be safe, but frankly I’d like to find something better. Many malware and other anti-virus programs have a file shredder built into them. Some have excellent ones.
However, I just found a very nice free one that is open source. It is called FileShredder. It has several excellent features opposed to the simple Shred it that I got from my AVG. It allows shredding of multiple files and folders at once. You can even make a folder for files that need be shredded and use it instead of the recycle bin for stuff you want to delete.
Simple and to the point, plus there is a help file on the webpage that is excellent.
This time when I shredded my experimental files, there were no leftovers, and searching did not bring up anything that could have pointed to them.
To get your copy of FileShredder, their website can be found here:
Please keep in mind, that there may still be copies of your files in your shadow files which are saved automatically when your system sets a restore point.
The fastest way to check these is through a program called Shadow Explorer which is free and can be downloaded here.
