Protecting Files

Safe Update uses file triggers to protect files. Whenever a program attempts to insert, update, or delete data in a file that Safe Update protects, it checks whether the change is allowed and stops those that are not.

To work with protected files, enter "1" on the command line of the Safe Update Main Menu screen. The Protect Physical Files screen appears.
