I have a folder in Media for pdfs. I updated some pdfs that I already had in there and have already linked to, but the links are not updating with the new pdf. I know when I update images in the Media section (basically, "write over" what was there) that it updates the images on the site - i.e. pulls in the new images. Is this not correct for pdfs? I'd hate to think I have to go in and manually re-link to all the new, updated pdfs.
