Interogate PDF files for attachment or portfolio structures

We have a portal where clients post documents to us. We wish to flag PDF's that are uploaded to us when they have either:

  1. Portfolio structure with attached files (PDF or otherwise)
  2. PDF with attachment(s)

We would like to list the files contained and extract as a secondary element.

Do you have a library that offers methods to assertain Portfolio PDF or PDF with attachments?

If so, please give me the name!

best regards,
