PDF Folders

Global PDF Folder

Hexo Assets are non-post files in the source folder, such as images, CSS or JavaScript files. For instance, If you are only going to have a few PDF files in the Hexo project, then the easiest way is to keep them in a source/pdfs directory. Then, you can preview(by Browser preview) or download them using something like

[pdf demo](/pdfs/pdf-demo.pdf).

Post PDF Folder

For users who expect to regularly serve PDF files, and for those who prefer to separate their PDF files on a post-per-post basis, Hexo also provides a more organized way to manage assets. This slightly more involved, but very convenient approach to asset management can be turned on by setting the post_asset_folder setting in _config.yml to true.
