read filename of attachments in a portable collection
My duty is: find all kinds of attachments in pdf files
After studying the examples I was able to detect the document-level and page-level attachments
But how do I detect the filename of attachments that are organized in a portable collection?
In the listings 16.9 - 16.14 is described how to create portable collections.
I could not found any stuff about analyzing the content of a portable collection.
