Org-mode - let it open .org files unfolded

Solution 1:

You should check the #+STARTUP directive for per-file default view settings:

• https://orgmode.org/manual/In_002dbuffer-Settings.html#In_002dbuffer-Settings

• https://orgmode.org/manual/Visibility-Cycling.html#Visibility-Cycling

You can use org-customize to set global defaults, or even use the VISIBILITY property inside a heading to affect a particular sub-tree.

Allowed values include: overview, content, showall, showeverything.

I don't recall an option for specifying a global N levels of visibility (you can put together some elisp for this); anyhow this is quite easy to do on the keyboard (e.g. M-3 S-TAB will display all headings up to level 3).

Solution 2:

In your dot emacs:-

(setq org-startup-folded "showall")

Solution 3:

Start-up folding is controlled by the org-startup-folded variable. It can also be set by placing:

#+STARTUP: fold
#+STARTUP: nofold
#+STARTUP: content
#+STARTUP: showeverything

any where in the buffer.
