Frequently Asked Question:
Generating a PDX for pdf files
Question
Any plans to add a function for generating an Index (.PDX file) for pdf files in a given set of folders?
Answer
The structure of PDX files is unfortunately not publicly available.
I believe Adobe licensed cataloging/indexing software from a company called Verity for Acrobat and Adobe Catalog, so at this stage PDX files can only be created / processed by Adobe software.
