I need to break this PDF into two separate files, but I don't know how to save just, e.g., pages 7-9. I tried "Print to File" but either did it incorrectly or it doesn't work.
When your file is open hit the "pages" tab on the left side of the screen, this should give you a list of page icons. Select the pages you want to save then "export" them, creating a new file with said pages. Or you could just delete all the pages you don't need and save over the old file.
With Reader? You can't. If you have an actual copy of Acrobat, you can use Document > Pages > Extract and specify the page range. This makes a new PDF of the pages you specified, then use File > Save As to save to disk.
