How do you insert a file?

Does anyone know how to insert a file on blogger? I have the option to insert link, picture, video, or a jump break, but not file. Thanks!

Yay!

I am officially a blogger! I am so excited to join the blogging community.  I love viewing teaching blogs to learn new strategies and get set-up ideas! It is truly bittersweet, because now I have five different ways I want to set up my reading area...which one do I choose! My new focus will be trying to figure out how to use a blog!
