Is there a way to do it? I use saveplace.el which puts me back to
the position where I was last time. I use nofold, so the place is
not hidden when opening the file. Currently, I'm satisfied with
this setup, but it would even be nicer if the previous folded
state was also restored.
Does org-mode have support for that?

No. Org-mode does not automatically save and restore the fold-state of a
file.
However, you can specify a default fold-state for particular
trees/subtrees by using the visibility property. See:
http://orgmode.org/manual/index.html#Visibility-cycling
Best,
Matt

Nope. As this is becoming a FAQ, I've added this sad answer to the
org-faq.org file in Worg.

I don't need this feature at the moment, but the problem
intrigued me, so I came up with a quick implementation.
I don't plan to work on it further, since I don't really need it
yet (I'm a novice org user), but I put it here if someone wants
to develop the idea.
You simply load the elisp file and from that on folding state is
automatically saved and restored for org mode files. The folding
information is saved at the end of the org file itself every time
the buffer is saved.
It seemed to work pretty well. The only faulty case I discovered
is when the very last branch is folded in the file, because it
contains the saved folding info, but this bug is probably easy to
fix with a little thinking.
Here it is. I hope someone takes the idea further:

Yes, I found this bug.
One way to work around this limitation and to safely store the folding
information would be to put it in a face property for each headline.
Perhaps you have time to dig into that direction?
Thanks for this proof-of-concept!

I wonder if it would be useful to have this information as an org-mode
COMMENT entry? Otherwise, functions like exporting etc will get
messed up?
Looks useful otherwise! Thanks,
eric

Unfortunately, I have more pressing matters to deal with
currently, but I also have a possible solution if someone has a a
little time to fix the package.
The folding information should simply be saved into a separate
file. For example, for notes.org the accompanying folding
information could be in notes.org.fold. The posted code can be
trivially modified to behave this way and with this change the
actual content of the org file is not affected at all and we have
a pretty usable folding save/restore extension for org.
This could be another advantage of org over other packages, since
this feature is pretty basic in my opinion and users usually look
for something like this.
P.S. If saving to a separate file is implemented then it is not
necessary to trigger storing of folding info with the save
hook. The user sometimes doesn't modify the file, only browses
it, so saving fold info when the buffer is closed would be the
perfect solution.

The thing pestered me, so I fixed it to take care of it.
Now folding information is saved into a separate file and it is
saved when the buffer is closed (but only if the buffer is saved
to disk to avoid saving folding info for discarded buffers).
I fixed the algorithm too, because it was buggy. Now it's working
well and it's also simpler.

Hey, that's nice.
I was just about to suggest: "Why not using a VISIBILITY property
for that?" (that would spare us the additional file..) but you were
faster than me! :)
Thanks for this,

Ah, yes. Properties. Being a new user I haven't yet used them,
so they didn't occur to me.
Anyway, we have a draft working implementation of the folding
restore feature, so it can be used to experiment with different
storage variants.

Sure! That's great to have this, I think many people will use it.

Hi "User",
this is great functionality, thanks for sharing it. I would like
to include it with Org-mode, s I need to ask: Do you have a
copyright assignment with the FSF? Or are you willing to sign one?
Thanks.

I don't have one and I doubt I'll have the time in these days to
deal with it.
The code is pretty trivial and short, so I think the best course
of action is that someone with proper legal status reimplements
it for org.

Getting one takes about 5 minutes now, and 5 minutes in a few weeks.

That is also a possibility, ok.
