Help with displaying embedded files/documents

Hi guys!

I just need a little help. I know how to display files and documents, such as videos (mp4, flv), documents (docx, xlxs, pptsx, odt, odp, pdf), within the files plugin.

However, I haven't figure out how to display such files and documents embedded in a comment. Can anyone give me a hint on how to do that? Which view do I have to extend?
