A little unknown feature called 'Batch Process...' can whizz through your PDF files changing anything from the way they open up to the page numbers they open up at.
Go to the File Menu and select 'Batch Process...'(see Figure 1.1), in here you will find options to update/create the Thumbnails in your PDF files, Optimize the PDF files or even set a password to your PDF files, the best thing about this is you can apply it to directories of PDF files.
