How to Create Your Own Shredding Algorithm

If you have been using Easy File Shredder for a while, then we are sure that you managed to check out all of its shredding methods. But what if you’d rather use a totally unique method? No problem – Easy File Shredder makes it easy to create your own shredding algorithm in seconds. The unique pattern of a custom shredding method will protect your deleted files in a unique way.

Creating a shredding method

Here is how you can create your own algorithm:

  1. Expand the algorithm selection drop-down menu and click on Configure
  2. In the new window, click on New to create a new algorithm
  3. Name the new method and enter a description
  4. Configure the shredding method by adding New Pattern, New Random or choosing a Random Method.
    Custom Algorithm

Now you can shred files and free space using your own, custom-made shredding method.

Which Shredding Method to Choose?

In this post, we are going to explain how different shredding methods work. This will help you select the algorithm that best suits your needs. Different files contain different information. While you may want to delete a private photo in a relatively quick way, deleting files that contain your financial information requires more advanced shredding, so that your bank statements can’t be undeleted even by professional hackers.

How to choose a file shredding method

Easy File Shredder provides a vast choice of different shredding methods that delete your data in different number of passes, using various overwriting methods. You can select a shredding method from the drop-down menu of the scan window:


When deleting files with Easy File Shredder, you can select one of the following shredding algorithms:

  • Bruce Schneier’s Algorithm – a data deletion algorithm created by Bruce Schneier. It overwrites information in seven passes.
  • German VSITR – data deletion algorithm released by the German Federal Office. Overwrites data in seven passes.
  • ITSG 06 – originally published by Communication Security Establishment Canada (CSEC), this method shreds data in three passes.
  • Peter Gutmann’s Algorithm – a shredding method by Peter Gutmann that overwrites data in 35 passes. This method offers high security, but it can take a while to complete.
  • Russian GOST P50739-95 – a Russian government approved shredding method that overwrites data in two passes.
  • US Air Force 5020 – a method defined in the Air Force System Security Instruction 5020. Overwrites data in three passes.
  • US Army AR380-19 – a US Army data deletion algorithm. Overwrites data in three passes.
  • US Dept of Defense DoD 5200.28 STD(7) – a United States Department of Defense standard.
  • US Dept of Defense DoD 5200.22 M(3) – a United States Department of Defense standard.
  • US Dept of Defense DoD 5200.22-M (E) – a United States Department of Defense standard.
  • US Dept of Defense DOD 5200.22-M(ECE) – a United States Department of Defense standard.
  • US DoD 5220.22-M(ECE) – a United States Department of Defense standard , overwrites in seven passes.
  • US DoD 5220.22-M(E) – a United States Department of Defense standard, overwrites data in three passes.
  • Custom shredding method
  • Random shredding method – overwrites data with random characters in one pass.

Basically, the more passes a shredding method uses, the more secure it is. But remember that more passes require more time to complete. So if you shred free disk space with Peter Gutmann method, be prepared for a long wait.

How to Scan Your Hard Drive for Deleted Files

Now you know how to shred files and free disk space. While shredding files is really quick (especially if you have one or two files to shred), shredding free space can take a long time. That’s why it’s best to shred free space only when there are deleted files that need to be wiped. Easy File Shredder can scan your hard drive for deleted files and let you know if there is a need to shred the free space or not. The program will display a list of detected deleted files, so that you will be able to decide whether you want to perform the shredding or not.

Scanning your hard drive for deleted files is easy:

  1. Launch Easy File Shredder and click on the Scan for Deleted Files icon
  2. Select the disk you want to scan and click on the Start Scanning button
  3. The disk you selected will be scanned for deleted files and you will see the list of recoverable files

How to Shred Free Space

In this post, I’ll show you how to shred free space to clean-wipe already delete files.

Why you need to shred free space

Clean-wiping your hard drive can be useful in many situations, especially when you are preparing your computer for sale. As you may already know, your deleted files that contained confidential information are not necessarily all gone. Some of them may have been overwritten with other files, but some of them are still there. You wouldn’t want your files to be recovered by someone, would you?

The best way to wipe everything from your hard drive is to format it. However, not all types of disk formatting delete all data from the disk. If you select a quick format method, your old data can still be recovered with the help of some file recovery software. Besides, you may not want to delete all files and programs including the operating system from your PC. If that’s the case, you should consider shredding free space with Easy File Shredder. Shredding free space will make traces of your deleted files unrecoverable without affecting any of your existing files or programs.

How to shred free space

Here is how you can shred free disk space with Easy File Shredder:

  1. Launch Easy File Shredder and click on the Shred Free Space icon
  2. Select the disk where you want to shred free space and then select the shredding algorithm from the drop-down menu
  3. Click on the Start Shredder button to start the shredding process
  4. The free space will be shredded and none of your deleted files will be recoverable

Now all traces of your deleted files will be deleted and you can safely sell or give away your old computer.
