问Android，为什么我看不到我刚写的文件？

EN

  String fileName = "Test6.txt";
    String outputString="Text for File";
    try {
        FileOutputStream outputStream = openFileOutput(fileName, Context.MODE_PRIVATE);
        outputStream.write(outputString.getBytes());
        outputStream.close();
    } catch (Exception e) {
        e.printStackTrace();
    }

                    try{
                    FileInputStream InputStream = openFileInput("Text6.txt");
                    InputStreamReader inputStreamReader = new InputStreamReader(InputStream);
                    BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
                    String lineData = bufferedReader.readLine();

                }catch(FileNotFoundException ex)
                {
                    Log.d(TAG, ex.getMessage());
                } 
                catch(IOException ex) {
                    Log.d(TAG, ex.getMessage());
                }

java.io.FileNotFoundException: /data/user/0/com.example.android.buildingmarque2/files/Text6.txt (No such file or directory)
