# Filter Password Protected Files

This section describes how to filter password-protected non-container files with the .NET API.

To filter password-protected files

- Use the `Password` property of the `Filter` class. Use the default `Filter()` constructor. For example:

      objFilter = new Filter();
      objFilter.Password = pwd;

  where `pwd` is a password of 255 or fewer characters.
