Besides inserting images, video and audio files you can also upload other file formats such as documents, PDF and PowerPoints directly into your posts and pages.

This doesn’t embed your file in your post or page so you can view it directly embedded in the post (or page); it inserts a link to the file.

When readers click on the link to the file it either opens up in another web browser or downloads the file onto their computer. This is handy for providing documents such as class notes, assignment information.

How do I add an external file to my post?

From your blog Dashboard or blog view, click on + New tab to open the drop-down menu
Select Post
Type a title for the post
Type your post into the input field
Go to the section of the post where you want your external file to appear and click on Upload/Insert icon above the text editor.
Select external files to upload
