How does the user get packet.exe?

I am confused about the how PB deals with the website from which users download the packet.
Let’s say I have created my packet (call it packet.exe) which contains my ebook (call it ebook.exe). Once packet.exe is on the user’s hard drive, I understand how everything works. But how does it get to the user’s hard drive? On the website, there must be a link that says Download Here. How does PB manage the download from the website to the user’s hard drive?

I think I got it – in the website a link to the executable packet, right?

Yes, exactly. Like we did for our installer packages on our websites.
