That seemed to do the trick. It seems very strange that Acrobat is unable to -1.) Sort pages by itself without the help of a third party application. That is a very basic function, especially for an application like Acrobat whose main function is to create large books and documents.2.) Unable to import separate PDF documents in order of their file names. The way Acrobat works now, it either imports separate pdf's backwards, and Acrobat has even imported pdf's in random order (for me at times, even when separate pdf files have been named in sequential numerical order).Those two issues should be addressed in any new versions of Acrobat.
