There is Linux under the hood, so the same file can in principle be in multiple folders (using a hard or a soft link, a single physical copy of the file can be listed in multiple directories). These would most likely look and behave like multiple copies of the file to the reader software (e.g. any metadata would be directory specific), but it is multiple copies without using any extra filesystem space.
