The hasClass method will accept an array of class names as an argument, you can do something like this:

$(document).ready(function() {
function filterFilesList() {
    var rows = $('.file-row');
    var checked = $("#filterControls :checkbox:checked");

    if (checked.length) {
        var criteriaCollection = [];

        checked.each(function() {
            criteriaCollection.push($(this).val());
        });

        rows.each(function() {
            var row = $(this);
            var rowMatch = row.hasClass(criteriaCollection);

            if (rowMatch) {
                row.show();
            } else {
                row.hide(200);
            }
        });
    } else {
        rows.each(function() {
            $(this).show();
        });
    }
}

    $("#filterControls :checkbox").click(filterFilesList);
    filterFilesList();
});
