File Shredder

File Shredder is another "must have" tool in yours "optimizing and securing your PC" collection software. File Shredder is free desktop application for shredding (destroying) unwanted files beyond recovery. With File Shredder you can remove files from your hard disk forever, without fear that files could be recovered. We always or ussually use the Windows command "Delete" to remove files from hard drive and deleted files go to Recycle Bin. But, the "delete" command in Windows only removes bits of information from files so they appear deleted in OS. It is easy to retrieve those files using specialized file recovery software. In order to remove, or shred files permanently from your system you have to use a program that is capable of rewriting the files with random series of binary data multiple times. This process is often called shredding. That way, the actual content of the file has been overwritten and the possibilities to recover such a shredded file are mostly theoretical. In File Shredder you can choose between 5 different shredding algorithms, each one gradually stronger than the previous one. It also has integrated Disk Wiper which uses shredding algorithm to wipe unused disk space. More info about this software is here and you can download it here.
