Answer 1

For security reason you can't write into the Application directory (for testing you can but it 's realy not recommended).

You can write into the Application Storage directory to store your application data.

• Use File then FileStream to write your data.

• To get the path of the file use nativePath.

  import flash.filesystem.File;
  import flash.filesystem.FileStream;
  import flash.filesystem.FileMode;
  import mx.controls.Alert;
  
  // get a file reference to the storage directory
  var file:File=File.applicationStorageDirectory.resolvePath("myfile.withextension");
  
  // create a file stream
  var fs:FileStream=new FileStream();
  
  // open the stream for writting
  fs.open(file, FileMode.WRITE);
  
  // write the string data down to the file
  fs.writeUTFBytes("my string to save");
  
  // ok close the file stream
  fs.close();
  
  // show the path to the file we have saved using Alert
  Alert.show(file.nativePath);
