Create a link to download a (Folder) with multiple files in it?

I am looking for a way to download a folder with multiple files in it with a link in Storyline.  I can link to a single pdf or other file that will download just fine, but how do I link to a folder with multiple files in it?

The only thing I can think of is to .zip it first then link to it... but is there any other way that someone knows about?

Thanks and regards
