When I populate listView from Array, why first is empty?

using System;
using System.Windows.Forms;
using System.IO;

namespace FolderContent
{
    public partial class frmMain : Form
    {
        public frmMain()
        {
            InitializeComponent();
            lblFileCount.Text = String.Empty;
        }
        string[] arrfilePathlist;
        // Select Folder/Directory
        private void btnBrowse_Click(object sender, EventArgs e)
        {
            // Clear text box
            txtPath.Clear();
            txtPath.Text = String.Empty;
            FolderBrowserDialog folderDialog = new FolderBrowserDialog();
            folderDialog.ShowNewFolderButton = false;
            folderDialog.RootFolder = Environment.SpecialFolder.MyComputer;
            folderDialog.Description = "Select the directory that you want to use";

            if (folderDialog.ShowDialog() == DialogResult.OK)
            {
                txtPath.Text = folderDialog.SelectedPath;

                // Use Dirctory.GetFiles method to get all files in directory
                // and, store in an array.
                arrfilePathlist = Directory.GetFiles(folderDialog.SelectedPath, "*.*");
                lblFileCount.Text = arrfilePathlist.Length.ToString();
                //uncomment next line to remove first empty row.
                //listView1.Items.RemoveAt(0);

                // Display items in the ListView control
                for(int i = 0; i < arrfilePathlist.Length; i++)
                {
                    listView1.Items.Add(Path.GetFileName(arrfilePathlist[i]));
                    //listView1.Items[0].SubItems.Add(Path.GetFileName(arrfilePathlist[i]));
                }
            }
            else
            { return; }
            
                // populate listview control with array.
        }
    }
}

listView1.Items.RemoveAt(0);
