That is a folder in my dropbox account that was created by Marvin when I linked to dropbox... although I'm not sure if it was Marvin 2.0 or 3.0 that created the folder?? The sync files that marvin created have similar names but are .r1 file types not .epub like yours. That's why I was wondering if they were sync files from calibre. They may also be files from other servers like itunes if you have them linked to your dropbox.
Since they ARE .epub files, have you used Sigil or Calibre Editor to open one of them up and see what it is?
