How to create Downloadable Zip file

We have a CD that we mail out to customers which contains 5 files that display a presentation of our company (similar to a powerpoint, but it was not created in ppt).

I would like to create a link in our flash site so that people could download a zip file to access this presentation. The presentation is about 300MB.

I am not sure how to go about this. I’m thinking I need to put the five files in a zip file, and create a button that links to this file on the server. Do I just create actionscript like this?

//Goto Webpage Behavior
//End Behavior

If so, then how does the user know which file to click on once it’s unzipped to run the presentation? I could create a text file with instructions, but I don’t know how many users will go through all the trouble.

Ideally, I’d like to create a link to the file and just have it play. Maybe the answer is really obvious here, but I’m new. Any help is appreciated. Thank you!
