"it doesn't work" does not give us much to go on. What did you expect and what did you get?

Did you see the code by following the link i have given? I expect the file should be downloaded from the server to visitor's computer of which is not happening now.

Well there could be a whole host of reasons. The main one is usually the file path. Try echoing out your filepath and filename and see if it is what you were expecting. I believe file_get_contents requires the full server path or a URL, not a relative path.
PS you may also want to add a check into your method that file_get_contents actually worked, and if not produce an error message.

Try this and see if it works for you.
PHP Code:
$path = '/uploads/docs/'.$name; // set the file path
force_download($path, null, true);
null - will read the contents from the path
true - will force the mime type to the filename

It seems "file_get_contents" has got a problem. So instead i tried this
$path = base_url('uploads/docs/'.$name); // Read the file's contents
The file is being downloaded to the pc properly but when i try to open it, its not opening. It becomes a corrupted file.
Why is this so and what could be the solution

When downloading files, never refer to a url, but always to a path, relative to the folder where your index.php is.
The reason why the file seems to be downloaded, is that CI thinks it's a new file. So, it will download it, but the file won't have any content.

First, make sure that you don't pass the filename directly to your controller, because it becomes part of the url.
The link in your view should be like this:
PHP Code:
echo anchor('download/download_file/' . urlencode($filename),$filename);
//the anchor function is in the url helper
Now, in the controller method, I decode the given filename.
PHP Code:
public function download_file($name)
{
//$name is the encoded filename, passed by the view
$this->load->helper('download');
$path = './uploads/docs/' . urldecode($name);
if (file_exists($path)) {
force_download($path,NULL);
}
else {
show_error('File not found!');
die();
}
}

Read the file with a text editor.
