        filePath = @"C:\ChangeLogs\" + DateTime.Now.ToString("yyyy-M-d") + ".txt";
        using (FileStream fs = File.Create(filePath));
    }

    async void OnContentInserted(ContentChangedEventArgs args) {
        TextSpan textSpan = await args.SubDocument.GetTextSpanAsync(args.Interval);
        File.AppendAllText(filePath,
            "'" + textSpan.Text + "': was inserted to " + args.SubDocument.Type.ToString() +'\n');
    }
