I’m assuming that you know about Scrivenings; if not, just ask. Then select Format > Options > Show Titles in Scrivenings. (That will give you the titles of all the folders and files which you’ve chosen, within the text; depending on how you’ve arranged your text, you may also have to go back to the Scrivenings and delete the titles you don’t want - although, as I’ve just discovered, that will also delete the same titles in the Binder, so that the files become untitled.)
