Copy the 200 files in a new folder and combine them.
I have been doing that, but that means I have to open up 1,922 pdf files to find the 200 files that I need. It takes too much time to open each pdf and extract it to another file. if there is a tag (same word or number in each of the 200 desired pdfs) is it possible to pull all pdfs that have the tag in a search?
You can perform a search in the Windows Explorer.
