Sorry, can't remember the names exactly, but I don't think they were the same.
All of that stuff, only 3 appeared in the menu bar pull-down, was in a folder with a name like "Domainsite.2" or such. It contained about 12-15 files.
May have been samples, I don't know, but the whole idea of Dropbox is to have "your own cloud-based folder" on the Dropbox server. I do not appreciate having "samples" inserted without my permission or knowledge.
Still can't find a way to provide feedback to Dropbox on this, very frustrating.
