Almost. Files are *opened* in some mode: if no other mode is
found, they are opened in fundamental mode - by themselves, they are not
"fundamental files" or "R-mode files" or ... That's an interpretation
that emacs superimposes on them when it visits them. To do that, it uses
information in auto-mode-alist, or in any mode specification in the file
itself (using file-local variables embedded in comments).
So when you open a file "foo", it will be opened in fundamental mode
(absent some other specification in the auto-mode-alist). When you add
contents, the mode does not change. If you save it as file "foo" and
then reopen it, it will still be in fundamental mode. But if you save
it as "foo.org" and then reopen it, the auto-mode-alist will tell emacs
to change the mode to org-mode (assuming that the .org suffix has been
set up correctly in the auto-mode-alist). It does not matter what the
contents were: it could be a C program e.g. and it would still be
opened in org mode.
