With PDF Explorer you can display the internal structure of a PDF file and explore its contents in an interface resembling Windows Explorer. PDF Explorer is a plug-in for use with Adobe Acrobat Exchange or Adobe Acrobat Reader. It allows you to explore the contents and internal structure of a PDF document. This plug-in is ideal for looking at resources used within a PDF file, such as fonts, bounding boxes, etc.

It would be of use to developers working with PDF files, or anyone who has an interest in the internal structure of such files. Before you can use PDF Explorer you must first open the PDF document whose contents and structure you wish to explore using this plug-in. Then select the PDF Explorer option from Exchange's Plug-Ins menu. Detailed information concerning the open PDF file is shown in the displayed dialog box.

The PDF Explorer dialog is split into two halves. On the left-hand side a tree view of all the low-level (COS) objects found within your PDF file is given. Initially this simply shows one entry, Document. Click on the plus sign next to this entry to expand the details. Keep clicking on the plus signs next to the items you are interested in until you reach the level of information you require.
