Whats the difference between using a shredding utility and deleting items using the trash can?
Throwing a file in the recycle bin does not remove the file contents from the hard disk it just removes the file name from the directory, leaving the data intact and vulnerable. In order to securely delete the file contents from the hard disk, you need to overwrite the area on the disk where the file contents are stored with other data. This is what ShredIt does. In addition, you need to ensure that you securely delete all copies of the file. When you edit a file, the application program will create and delete working copies each time you save, leaving mulitple copies of your file on the hard disk in the disk free space area. In order to securely delete these copies, you need to shred your free space. ShredIt also does this.
