If you have lots of PDF files on your Mac and are worried about dealing with “a cluttered mess” as CNET’s Topher Kessler puts it, you have options. In addition to spotlight’s indexing, smart folders or consolidating the files in one location, iTunes can also be used to manage a library of PDF documents.
Kessler looks at the merits of using iTunes to organize PDFs, as well as other Apple media support options. “Besides options that are built into OS X, there are a few programs out there that can help not only organize PDFs, but also other documents and information on your system,” writes Kessler. “One of these is the tool iDocument, which is very similar to iTunes, but is tailored for documents instead of media.
Other options include Yojimbo, which is a long-standing information organizer for OS X, and Yep, which was created by the developers of the popular maintenance program MacKeeper.”
