Sorry but there is no option in the forum to attach files. I suggest you upload them in an online file sharing service and send us the link. Example: https://jumpshare.com/
I do not want to insert Pdf file to the forum. I would like to put them on my web-site that I am creating with Tower topic. I would like to upload pdf files on the web so my potential customers can download it.
Sorry for misunderstanding your point.
No, there is no option on theme to include files. I suggest you install a custom plugin that enables this feature for you.
