-Now paste the following code into the button1_click event i.e. private void button1_Click(Object sender,EventArgs e){

folderBrowserDialog1 = new FolderBrowserDialog(); //to implement a new folder browser

DialogResult result = folderBrowserDialog1.ShowDialog();  
if (result == DialogResult.OK)                              
String[] allFiles = System.IO.Directory.GetFiles(folderBrowserDialog1.SelectedPath);  //store the files in the string array

for(int i=0;i
listBox1.Items.Add(allFiles[i]);         // use the for loop to continously add the file addresses to the listbox
