title_body: What does it mean that a pdf is "paginated"? I have quite often seen written somewhere that pdf is (or isn't) paginated. Maybe this term is used for other formats, too.
  
  I thought that this is used to pdf where page numbering in the file corresponds to the page numbers in the actual document. (To explain in layman's terms, if it as book and the frontmatter is numbered as i-xiv and the rest of the book is numbered 1-400, then when I try to go to page number 1 in the viewer, it goes to the first page of the book, not the first page of the frontmatter.)
  
  But I have also seen this post on another SE site. The answer given seems to indicate that non-paginated pdf would mean that it is a file which consists only of single very long page.
  
  To clarify the things:
  
  
    What is the meaning of the term paginated pdf-file. If both usages mentioned above are correct, which of them is more common?
upvoted_answer: I have never heard it used to mean either of those things. In my experience, if someone says a PDF is paginated, they simply mean that there are page numbers on the PDF's pages. They may or may not correspond to some other publication, like a physical book. The point is simply that the pages have numbers on the pages themselves.
