Adding html files & folders

Hi Gurus,
I have need to be able to embed keynote slides onto my wordpress site.
I am exporting from Keynotes into HTML, which results in a folder of “content” and a html “index.htm” which runs perfectly from a web browser.
I want to be able to upload this folders of html files INTO the file structure / hosting server and then link and access them from within the published pages.
Uploading the files onto the hosting server is no issue, all done, but how the DEVIL do I get wordpress to bring those files through into the pages and posts??
