I want to upload files to their normal directory under sites/sites/default/files/. So let's assume I have example.pdf uploaded to sites/sites/default/files/manuals/example.pdf.

I don't want to alter the place image is put on hard drive. But I want my links to files to look like http://example.com/manuals/example.pdf - I think it's simpler and looks more professional. How can I achieve it with Drupal?
