title: Android - Download all files from a folder on server
body: <p>Hope I am able to explain this correctly... 
  I am able to connect to my web server and download a single file.What I am now attempting to do is connect to my server and download all the flies from a particular folder.In this case i want to download images.
  This is the code i use to download a single file...</p>
  
  <pre><code>URL url  = new URL("http://127.0.0.1/Folder/file.csv");
              URLConnection conexion = url.openConnection();
              conexion.connect();
              int lenghtOfFile = conexion.getContentLength();
              InputStream is = url.openStream();
              File testDirectory = 
              new File(Environment.getExternalStorageDirectory()+"/Folder");
              if(!testDirectory.exists()){
                  testDirectory.mkdir();
              }
              FileOutputStream fos = new FileOutputStream(testDirectory+"/file.csv");
              byte data[] = new byte[1024];
              int count = 0;
              long total = 0;
              int progress = 0;
              while ((count=is.read(data)) != -1){
                  total += count;
                  int progress_temp = (int)total*100/lenghtOfFile;
                  if(progress_temp%10 == 0 &amp;&amp; progress != progress_temp){
                      progress = progress_temp;
                  }
                  fos.write(data, 0, count);
              }
              is.close();
              fos.close();
  </code></pre>
  
  <p>How can I add to this code to make it download all the files from that folder?</p>
