How can I create an HTML file in which it can cause all my compiled digital birthday card (executable file)?

All my digital books, or greeting cards are compact, self-contained, Windows program.  But whenever I uses a website in which I can enable all my digital birthday card with the Surprise to be on temporal display for customers to evaluate prior to his or her purchase.  They may be able to see what is inside the surprise: an interactive jigsaw puzzle, or a video of actions, etc.  They will know which digital product they want to buy.  But, however, the website I am working on by inserting one of a digital birthday card inside the URL, but they cannot reach any of my digital birthday card for it is on my drive C.  I know that any URL inside the Internet Browser - would require a HTML product that can upload one of my digital birthday card (executable file). I wonder if you do have a form that enable any customer to evaluate any of digital birthday card, or any digital book with the understanding that any digital product cannot be stolen without making a purchase.  Do you understand what I have tried to give an explanation?

Here is a sample of .  and

a photo of an orangutan with baby white leopards has been converted into the software of an Interactive Jigsaw Puzzle (which it is actually an executable file (*.exe)   But you can see how often customers come to the Safeway where there is a couple of shelves of variety birthday cards and customers can evaluate by looking what is the surprise inside without making a purchase.  Why we cannot do in the creation of such a website of shopping cart?

Eagerly be hearing from you very sooner.

If your digital birthday card is an executable file then it can only be run by an operating system. It cannot be opened or run in the browser. Your users need to download the .exe file to their computer. So, you need to upload the file first to your web server and then provide the direct link to your users.

You can insert an external link in the form using the "Text" tool. Please check this guide: https://www.jotform.com/help/431-How-to-Add-a-Downloadable-File-to-Your-Form

Hope that helps. Thank you.
