    {
    
    
        string path = Application.dataPath + "/TextFile/TextFile.txt";

        FileStream file = new FileStream(path, FileMode.Create);

        byte[] bts = System.Text.Encoding.UTF8.GetBytes(text);

        file.Write(bts, 0, bts.Length);

        if(file!=null)
        {
    
    
            file.Flush();
            file.Close();
