secure file deletion


CyberShredder – added 11/15/2005

CyberShredder is a quick, safe and handy utility that lets you erase confidential files from your computer permanently. Normal file deletion will remove a file’s directory entry and allocation table information. The actual disk clusters that contained the file’s data remains intact on your hard disk and can be recovered later. CyberShredder overwrites the space occupied from a file with random data and erases the file, so an unerase utility will never be able to recover it.


Delete Doctor – added 9/3/2005

Delete files that are difficult to delete, such as some files left by viruses and trojans, or files with corrupted file names. This program can also delete files like the “index.dat” files, which store Internet history, by scheduling them for deletion upon system restart. Select a file to delete from the built-in file browser or drag a file to the application’s icon or window from Window’s Explorer.


Scrub – added 5/23/2005


Scrub is a multi-pass secure file remover. When you delete a file normally, all that happens is the system reports the space taken by the file as available. The file is still there until you overwrite it by saving other files or data. Scrub protects your privacy by overwriting the file the selected number of times using varying bit patterns, setting the file size to 0 and overwriting the file name.


CHAOS Shredder – added 5/19/2005

CHAOS Shredder allows you to purge, wipe and erase data with methods that far exceed US Department of Defense standards for file deletion (DOD 5220.22). By overwriting the portion on the hard drive that was previously allocated to the files several times with junk data, CHAOS Shredder will completely erase files from your disk, without the possibility to recover it by any practical software or hardware methods.


SuperShredder – added 9/19/2004

SuperShredder gives you the ability to delete files using not only common methods such as Gutmann and NISPOM (DoD), but can be completely customized to give you all the security you may need. It can receive files via drag-and-drop onto the application or the icon, selecting files from inside the program, command line, and can even add a shortcut to your ‘Send To’ menu inside the Windows Explorer.


AbsoluteShield File Shredder – added 8/29/2003

Windows does not physically remove deleted files from your hard disk. Emptying your Recycle Bin does NOT protect you at all. Your sensitive files can be recovered, even after you format your hard disk! When you delete a file from Windows, Windows just mark the file as deleted in file allocation table, but the data of the file is still in your hard disk, there are many tools available which can let others easily recover your sensitive files even you format your hard disk.


Shredder – added 437K

When you delete a file it is not immediately removed from the hard drive. Only it’s place in the File Allocation Table (FAT) is removed. The FAT is similar to a Table of Contents in an extremely large book. If you removed an item from it you would have a very hard time finding it in the book. Deleting a file and removing it from the FAT informs Windows that this space is available for overwriting. It will be overwritten the next time you copy something that is the same size or smaller.
