The way it works is that you make a page in wordpress. On that page, you can put whatever you want (links to downloads, text, whatever). Also, you can put a shortcode that will cause a form to appear on the page. You create that form in Contact Form 7. The form must include a field for name & email address & a submit button.
So, when a web surfer visits your wordpress page, it will display whatever you put in the page, plus the form you made, which will have name & email address & a submit button. If you have set it up for multiple downloads (multiples files), then your files will be listed with a checkbox next to each one (the user checks which files he’s interested in). The user fills in his name & his email address & hits submit. At this point, it might display a link to a single file or to multiple files (if set up that way) that the user checked & then he can click the links to download the files. Or, it might send an email with the link or links. Or it might do both. Or it might attach the files to the email. All of that depends on what you’ve chosen as options & how you have set it up.
What is does not do is remember anything from page to page. So, if you have 3 completely separate pages, each with its own form & to download a file (or several files, whatever), then the user will have to re-enter his email address on each page. There is no cookie set to remember the entries from one page to the next. Thus, either your user will have to re-enter, or you will need to figure out a way that it makes sense to offer all your downloads on a single page.
This plugin is not the simplest thing to set up properly. I suggest you spend a significant amount of time reading & re-reading the Description, FAQ, Screenshots, and a bunch of the support items before you try to get it working right…
Good luck
