I don't know exactly what the situation is, but the short answer is "no". Assuming you used Main as a data pack when you created your new module, the mod will default to settings used in the main campaign (reading from the .paks, as D:OS itself does). More folders in \Data\Mods\ will appear automatically as you start adding your own dialogs, scripts, book-texts, etc.
You will start adding folders from the Unpacked stuff as you customise things, examples... character.txt for giving unique stats, skillset.txt for customising what skills a character has in their hotbar, lots of other, more adventurous (intelligent) stuff) and that will involve you opening the unpacked .txt file and using it as a template to add your edits to, then dropping it into the correct place in the Data\Public\ section. I'm a little pushed for time right now, so you'll have to read around a little bit to figure that out, or maybe a kind soul will come into this thread and bullet point the basics for you.
EDIT: one last thing, you can now go into those unpacked files and explore (most of) them at your leisure. I think everyone here at some point has gone into the \Mods\Main\Story\RawFiles\Goals of their unpacked files to sift through the devs' coding in a bid to figure out how to make something work, ha.
