Hi,@Scott Q-0525. You could try the following code:

<StackPanel>
    
        <Button Content="show" HorizontalAlignment="Left" Margin="355,60,0,0" VerticalAlignment="Top" Click="Button_Click_1"/>

        <RichTextBox Name="myTestRichTextBox"  AcceptsReturn="True"  Height="100">
            <FlowDocument>
                <Paragraph>
                    <Run Text="RichTextBox"/>
                </Paragraph>
            </FlowDocument>
        </RichTextBox>


    </StackPanel>

  string filePath = "C:\\...\\example.rtf";
       
        

        private void Button_Click_1(object sender, RoutedEventArgs e)
        {
           
                TextRange range;
                System.IO.FileStream fStream;
                    range = new TextRange(myTestRichTextBox.Document.ContentStart, myTestRichTextBox.Document.ContentEnd);
                    fStream = new System.IO.FileStream(filePath, System.IO.FileMode.OpenOrCreate);
                    range.Load(fStream, System.Windows.DataFormats.Rtf);

                    fStream.Close();
                
            

        }

The result:
