Sure, how about this? If by 'below' you mean as displayed (48..n) is 'below' 47
       private void Form1_Load(object sender, EventArgs e)
        {
            string [] lines = new string[richTextBox1.Lines.Length];

            if (richTextBox1.Lines.Length > 47)
            {
                Array.Copy(richTextBox1.Lines, 48, lines, 0, richTextBox1.Lines.Length - 48);
                richTextBox2.Lines = lines;
                lines = new string[48];

                Array.Copy(richTextBox1.Lines, lines,48 );
                richTextBox1.Lines = lines;
            }
        }
 
If you mean below is lines 0-46 then just change the logic to get the lines <47. OR, just swap the two arrays after running this code.
