Have you tried just selecting the binder items whose titles you want to capture, and pressing Ctrl+C / ⌘C, then pasting into whatever program you want?
You might also consider a more useful marking scheme in the future than depending upon the folder/file difference. That isn’t really something you can search for, or do much with (they are all “binder content” as you put). But if you give the item a colour Label or something of that nature, then you can run a search for that label, get a tidy list of them, and copy and paste from that.
Or, use the contents of that search result list to compile from, and avoid the extended unorthodox configuration. If you’re compiling from the search result list alone, then the list only has what you want. You can then use a stock Format like Enumerated Outline, or one of the other outliner oriented formats, which has title-only layouts built already.
If any of that sounds feasible and you aren’t sure how to do it, let me know.
