  Hi Juan,
  I have some example code that downloads chart images from the net. The images are saved locally. I have image views inside regular views that have to be updated with the chart images. Here's the code:

  var xhr = Ti.Network.createHTTPClient();
  xhr.onload = function()
  {
      oldf = Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory,'chart.png');
      if (oldf != null) {
        oldf.deleteFile();
      }
      f = Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory,'chart.png');
      f.write(this.responseData);
      myView.remove(myImageView);
      myImageView = Ti.UI.createImageView();
      myImageView.url = f.nativePath;
      myView.add(myImageView);
  };
  xhr.open('GET',imageUrl);
  xhr.send();
  

  Hope this helps.

• You currently use

  Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory,'chart.png');
  

  , which means that you know the name and extension of the file. What happens in a situation, where you select a file from the list, so you want to get a file that you do not know the name and extension for ?

  I was trying something like this :

  var mediafile = Ti.Filesystem.getFile(tempDir.nativePath, Ti.Filesystem.getFile(tempDir.nativePath).name);
  

  but how do I get file extension for it ?
