I discovered a neat trick in Acrobat recently that I wanted to share with you. In addition to using the Pages panel to copy/paste/move between open PDF documents, you can also drag and drop a PDF from the desktop (or a folder) into an open PDF, as well as drag and drop from an open PDF to the desktop to create a new PDF document.
This tip is also available as a video.

Let’s start with adding new pages to an open document. I have an open PDF document and a PDF file on my desktop (Figure 1). I can select the two-page file — PPT for Project.pdf — from my desktop, then drag and drop it onto the Pages panel of the open PDF to automatically add new pages (Figure 2).
Alternatively, I can select a page or pages from an open PDF (Figure 3) and drag this selection onto the desktop, creating a new PDF from the selection automatically (Figure 4).
