How to hide the path for .zip files?

Hello,

I put all .zip files in folder /zipFiles/ of my ASP site (ASP.Net code also works).
How to hide the path of the .zip files in my ASP site?
Now, a visitor can see the path of the .zip file related to an article something like
http://www.....com/zipFiles/file1.zip
(When he set curser on it or from the source)

I do like visitors to download that .zip file when he read the article. However, don't want visitors know the path of the .zip files!

Thanks a lot for your help!
