Does anyone can help me with code, how to delete the file after file is downloaded successfully, I was look in google and can't find clean solution.

Hello. You have to download the file with a PHP, so when the file were downloaded, you could make a unlink(). See http://w-shadow.com/blog/2007/08/12/how-...-with-php/ for example for PHP or see Download Helper

If it's just a plain text file, you don't need to create an actual file.
Just generate the content and use the download helper: user guide

Code:

// generate the content, use a model function or whatever
$content = generate_content();
$this->load->helper('download');
// send the file to the user
force_download('some_file.txt', $content);
