[O] What might open some org file?

[Marcin Borkowski]

Hi there,

I have a strange problem.  When I hit C-a a (org-agenda), Emacs opens
some org files not present in org-agenda-files (which contains only one
directory).  One of these files is mentioned (in the form of a link) in
one of the agenda files, but the other one is not.

How is that possible?

TIA,
