Can I make a Custom Action to combine PDFs of multiple folders?

[klumas]

I have a bunch of folders with multiple PDFs files inside of them. I need combine the PDFs in each folder together. To be clear the contents of each folder need to stay seperate from one another, so I need to end up with as many PDFs as there are folders. Is it possible to create an Adobe Action to automate this? Or is there some other way to automate this? 

Also, if possible, I'd like to name the PDF the same as the folder it is "distilled" from.

Other Information that may matter: These PDFs are all scanned from paper. The paper doesn't come at the same time, and is ongoing, so I can't just scan the necessary pages all at once into one PDF.

No, an Action can only work on either a group of files, or a selected folder, it cannot process a folder and then jump into subfolders and so on. That's the case as long as you stay within Acrobat. If you however step outside of Acrobat and create e.g. a Visual Basic application that then traverses the filesystem and then calls Acrobat to combine the files in each folder, you can get around this security restriction. It does however require you to know how to program in VB and how to use the Acrobat API. As far as I know, that's the only way to do this with Acrobat.

It's only possible using a combination of an Action with a separate script. See this (paid-for) tool I've developed that does just that: http://try67.blogspot.com/2010/10/acrobat-batch-combine-all-files-in.html
