in the future, to find the best place to post your message, use the list here, https://community.adobe.com/

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.

Make sure none of the files is digitally signed.

Sim , tem arquivos assinados digitalmente. Nesse caso como combinar os arquivos assinados digitalmente ?

Only as a Portfolio, which I'm not sure is possible through the online interface of Acrobat. You might have to use the desktop application.
