Can you use a dialog to open both folders and files?

Question

Well, I’m using the openfiledialog to open files, however the software needs to receive files or folders, because it compressed and zipped (.zip) and then make a symmetrical cipher.

I have searched several sites and the like, and I haven’t found a way to use the same dialog to open both types.

private void btn_criptografar_Click(object sender, EventArgs e)
    {
        //Abre o dialogo para abrir arquivos e pastas.
        if (openFileCrypt.ShowDialog() == System.Windows.Forms.DialogResult.OK)
        {
            textBoxShowPath.Text = openFileCrypt.FileName;

            FileStream inStream = File.OpenRead(textBoxShowPath.Text);

Answer 1

It is not possible in standard control, have to develop a new one that does this. Have a example how it can be in a library that works justly with zip files (isolated project).

Other project that does the same.
