Create multiple folders named after the Items of a ListBox

Clicking on the the Get List Button:

  1. I fill a ListBox with the file names contained ina a selected.
  2. I then separate the files extensions and fille another ListBox, removing the dot.

Clicking on the Create Folders Button,

I want to remove the duplicate extensions and create folders named after the items in the ListBox.
i.e., create folders with names: doc, docx, dwg etc. 

private void btn_list_Click(object sender, EventArgs e)
{
    listBox_ex.Items.Clear();
    FolderBrowserDialog FBD = new FolderBrowserDialog();
    if (FBD.ShowDialog() == System.Windows.Forms.DialogResult.OK)
    {
        lbl_path.Text = FBD.SelectedPath;
        listBox_name.Items.Clear();
        string[] filename = Directory.GetFiles(FBD.SelectedPath);

        foreach (string file in filename)
        {
            listBox_name.Items.Add(Path.GetFileName(file));
            listBox_ex.Items.Add(Path.GetExtension(file).Replace(".", ""));                  
        }
    }
}

private void btn_CreateFolder_Click(object sender, EventArgs e)
{
    FolderBrowserDialog FBD2 = new FolderBrowserDialog();
    if (FBD2.ShowDialog() == System.Windows.Forms.DialogResult.OK)
    {
        lbl_pathCreated.Text = FBD2.SelectedPath;
    }

    string path = lbl_pathCreated.Text;
    if (!Directory.Exists(path)) {
        Directory.CreateDirectory(path);
    } else {
        MessageBox.Show("already exit");
    }
}

Alternative method, using 2 List<string> objects to store the current files' selection and the files extensions as Distinct, Ordered elements.

The Lists are then used as the ListBox.DataSource.
A ListBox.Items collecton is reset when the DataSource is changed.

When a destination Path is selected, each item in the List of extensions is used to create a Directory in the selected path.
No need to check whether the Directory already exists: Directory.CreateDirectory() just ignores it.

You might want to add a validation procedure for the Path a user seleted. The user may have picked a weird destination. 

List<string> fileNames = null;
List<string> fileExtensions = null;

private void btn_list_Click(object sender, EventArgs e)
{
    using (FolderBrowserDialog fbd = new FolderBrowserDialog())
    {
        if (fbd.ShowDialog() == DialogResult.OK)
        {
            lbl_path.Text = fbd.SelectedPath;
            fileNames = Directory.GetFiles(fbd.SelectedPath).ToList();
            fileExtensions = fileNames.Select(item => 
                Path.GetExtension(item).Replace(".", "")).Distinct().OrderBy(n => n).ToList();
            listBox_name..DataSource = fileNames.Select(f => Path.GetFileName(f)).ToList();
            listBox_ex.DataSource = fileExtensions;
        }
    }
}

private void btn_CreateFolder_Click(object sender, EventArgs e)
{
    using (FolderBrowserDialog fbd = new FolderBrowserDialog())
    {
        if (fbd.ShowDialog() == DialogResult.OK)
        {
            lbl_pathCreated.Text = fbd.SelectedPath;
            fileExtensions.ForEach(item => 
                Directory.CreateDirectory(Path.Combine(fbd.SelectedPath, item)));
        }
    }
}
