How to add "Download" button instead of "Add to cart" one

[m_mbarakota]

i had a library selling e-books
some for free and i wish that "FREE products" can be directly downloaded without add to cart then checkout process

if anyone can help me to change "Add to cart" button to "Download" Button
sure not the button picture only, but the link button redirect to.

OR
if it can't be done to some products Only
how to make it for "ALL PRODUCTS" as i can setup an ordinary zen cart for the paid products
and another one for all free products

Or
suggest a script to me that looks like zen cart , contain admin panel and easy as zen cart, and let users download each free product directly from a link in the page without add to cart and check out process


i know it's a complex lil bit lol but thx anyway
