        }

        private void button2_Click(object sender, EventArgs e)
        {

            Visible = false;
        }

}

Form 2:

C#

        public Form2()

        {
            InitializeComponent();
        }

        public static int GetFileCount()
        {
            var fileCount = 0;
            var fileIter = Directory.EnumerateFiles(Form1.folderPath);
            foreach (var file in fileIter)
                fileCount++;
            return fileCount;
        }
        public static int GetDirectoryCount()
        {
            var directoryCount = 0;
            var directoryIter = Directory.EnumerateDirectories(Form1.folderPath);
            foreach (var directory in directoryIter)
                directoryCount++;
            return directoryCount;
        }

        private void richTextBox1_Load(object sender, EventArgs e)
        {

            richTextBox1.Text = "Directories:" + GetDirectoryCount() + Environment.NewLine + "Files:" + GetFileCount();
        }
    }
}

First, assuming Form1 is the main form, and you hide it, how will you show it again unless Form2 has a reference to it ? Do you really need to show a second Form ?

private void richTextBox1_Load(object sender, EventArgs e)
{
    richTextBox1.Text = "Directories:" + GetDirectoryCount() + Environment.NewLine + "Files:" + GetFileCount();
}

A RichTextBox has no 'Load Event: this should be the Form2 'Load Event.

Why let the user show Form2 without making sure you have a valid Path:

public void button1_Click(object sender, EventArgs e)
{
    button2.Enabled = false;

    FolderBrowserDialog folder = new FolderBrowserDialog();

    if (folder.ShowDialog() == DialogResult.OK)
    {
        folderPath = Path.GetDirectoryName(folder.SelectedPath);
        textBox1.Text = folderPath;

        button2.Enabled = true;
    }
    else
    {
        // throw an error ?
    }
}

You can use these forms to simplify your Form2 methods:

return Directory.GetFiles(folderPath).Length;

return Directory.GetDirectories(folderPath).Length;
