18.2. Creating custom algorithms of data destruction

File Shredder gives you the opportunity to create your own algorithms for wiping hard disks.

Although the software includes several levels of data destruction, you can choose to create your own.

This is recommended only for users familiar with the principles of data destruction used in secure disk

wiping methods.

Creating a custom method of hard disk wiping is possible after choosing "Custom…" from the drop-

down list in the Algorithm selection window. In this case some new required steps appear in the File

Shredder wizard and you will be able to create a data destruction algorithm matching your security

requirements.

Having created a custom method, you can save the algorithm you created. This will be handy if you

are going to use it again.

To save your algorithm, you need to give it a filename and show the path to the folder you want to

store it in by selecting the folder from the tree shown in the left pane.

Each custom algorithm is stored in a separate file with its own name. If you try to write a new algorithm to a

pre-existing file, the existing file's contents will be erased.

If you created and saved your algorithm for data destruction while working with File Shredder, you

can use it later in the following way:

• In the Algorithm selection window, choose Load from file… from the drop-down list and select

the file with custom data destruction algorithm parameters. By default, such files have a *.alg

extension.
