Additionally, the software includes the Wiping Scheme Editor utility to view and edit number of wiping passes and binary patterns used at each pass.

To create new scheme - press New button and specify a name of your scheme. The picture illustrates creation of custom wiping scheme called ‘My wiping scheme’. BCWipe performs 7 passes of wiping when it shreds information according to the scheme. 11 passes means that BCWipe overwrites the information 7 times, and uses different byte patterns for overwriting. For example, in the first and the last (7-th) passes BCWipe uses random bytes to overwrite data.

Then set
Random radio button - if you wish to use random bytes for overwriting;
Complementary - if you wish to use byte pattern complementary to the previous pass;
Cycled byte patterns - if you wish to set a concrete byte patterns for the wiping pass;

To insert additional pass to the scheme, press the Add button.

To update existing pass, select the pass in the list of passes and press the Update button.

To remove a pass from the wiping scheme, select the pass in the list of passes and press the Remove button.

When you finish editing the wiping scheme, press the Apply button to make BCWipe apply the new settings.

Procedure of saving the scheme to file is called Export, and procedure of loading wiping scheme from file is called Import .
