Open a existent pdf file using CI

[eluser]Thiago Luiz[/eluser]
Solved the problem. I put the subfolder where the pdf file on the same level of the CI system folder and again tried to use that Adi Setiawan said:

$ this-> load-> helper ( 'download');
$ data = file_get_contents ( "subfolder / file.pdf");
$ name = 'file.pdf';
force_download ($ name, $ date);

And it worked, now I can load through a view open a pdf file.
