Can't find saved file in data/data/package name

Question

I'm saving a hello.txt file with strings inside. But I cant find it in DDMS>selecting my package name in devices>File Explorer>data>data>package name.

Even my package name is cut. My package name is bla.Test9 but it only shows bla. Also under data/data it shows a lot of con folder, jps, and bla folder. Tried to ipen bla folder but I can't find the hello.txt inside

public void save(View v) {

        TextView dat = (TextView) findViewById(R.id.textView1);
        TextView gdat = (TextView) findViewById(R.id.textView2);
        TextView name = (TextView) findViewById(R.id.textView3);
        EditText gname = (EditText) findViewById(R.id.editText1);   

        String s1, s2, s3, s4;

        s1 = dat.getText().toString();
        s2 = gdat.getText().toString();
        s3 = name.getText().toString();
        s4 = gname.getText().toString();

        FileOutputStream fos = null;

        try {
            file = getFilesDir();
            fos = openFileOutput("hello.txt", Context.MODE_PRIVATE);
            fos.write(s1.getBytes());
            fos.write(s2.getBytes());
            fos.write(s3.getBytes());
            fos.write(s4.getBytes());
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        finally {
            try {
                fos.close();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }   
    }

EDIT: I'm using an emulator not a device.

LOL. Solved it. I just extend the window of name column in file explorer. Now i know why the names are cut.
