Question

EDIT: It turns out that the second edit to my .emacs file actually works. (See the comments below this entry.)

I tried a couple of addition to the .emacs to make all txt files opened in emacs use orgmode. They did not work. How can I make it happen?

;;SET EMACS AS DEFAULT MAJOR MODE TO FOR ALL FILES WITH AN UNSPECIFIED MODE
(setq default-major-mode 'org-mode)

;;OPEN ALL TXT FILES IN ORGMODE
(add-to-list 'auto-mode-alist '("\\.txt$" . org-mode))

Additionally:

It would be even better to open only txt files in a certain directory orgmode. Any hint as to how that could be done would also be appreciated.

You can implement a hook which verifies the file directory and modifies the buffer mode:

(add-hook 'find-file-hooks 
          (lambda ()
            (let ((file (buffer-file-name)))
              (when (and file (equal (file-name-directory file) "c:/temp/"))
                (org-mode)))))

As an alternative you can add the mode line in the beginning of your text file. In this case emacs will set the specified mode.

; -*- mode: org;-*-
* header 1
** header 2
