I have imported several PDF documents into PDFClerk Pro.  Each of these documents had a varyng number of pages, and they show up as a series of named documents (sections,) each starting with page 1.  What I need as a result is one long document with page numbers running from 1 right through - across the sections )- to the end.  I took at look at the online manual, but the instructions for getting to the document setting panel didn’t match with the demo I had (maybe a different version)  Can you help please?

Sure,

First, you need to get the labels in order:
- Select all the pages in the page list. (Click any page in the list, then hit Command-A.)
- Control-click (or right-click) the list to bring up the contextual menu.
- Click “Relabel Selected Pages”
- The default values in the ensuing dialog are probably just what is appropriate for you, so click the OK button.

The labels should now be sequentially numbered, starting with 1.

Now you need to make the labels appear on the page:
- Bring up the Document Settings Editor. (control-option-command-D)
- Select the Labels tab.
- Adjust the settings as appropriate and click the OK button.

You should now have the page labels appearing on the pages.

Thank you for the very clear answer - and I am delighted!  Works just as you explained.  This does the trick and I’m ordering it now online.  This is customer service at its best (the product too)

I was searching for the same problem and found this post.
I also did as you explained and guess what I’ve got the results.
Thanks for this wonderful on line support.
