Some iOS Native extensions that can be useful

First of all, thank you for creating this extension. However, it doesn't seem to work. Below is my code for decompressing ByteArray (error handling is stripped for simplicity):

                    public function decompress(aData:ByteArray):ByteArray {

                              // Save data to file

                              var fileInput:File = File.applicationStorageDirectory.resolvePath("input.7z");

                              var stream:FileStream = new FileStream();

                              stream.open(fileInput, FileMode.WRITE);

                              stream.writeBytes(aData);

                              stream.close();

                              var folderOutput:File = File.applicationStorageDirectory.resolvePath("output");

                              ANE7z.decompress(fileInput, folderOutput);

                              var files:Array = folderOutput.getDirectoryListing();

                              for each (var fileOutput:File in files) {

                                        trace("Extracted file: " + fileOutput.nativePath);

                                        if (!fileOutput.isDirectory) {

                                                  var bytes:ByteArray = new ByteArray();

                                                  stream = new FileStream();

                                                  stream.open(fileOutput, FileMode.READ);

                                                  stream.readBytes(bytes);

                                                  stream.close();

                                                  bytes.position = 0;

                                                  return bytes;

                                        }

                              }

                              return null;

                    }

The problem is folderOutput.getDirectoryListing() always returns an empty array.
