Vim has excellent folding support. There is good documentation in the vim help system. Just open vim and do

:help usr_28.txt

After reading that you can also read

:help folding

for some more information.

Yes. VIM has exceptional folding capabilities. I don't like learning too many controls, I prefer automation, so here is what I personally use:

In my .vimrc:

set foldmethod=indent
set foldlevel=1
set foldclose=all

This automatically folds files that you open, based on indent, for everything indented for more than 1 level. The foldclose option makes the fold automatically re-close after I navigate out of the fold.

In-file Controls:

zo - opens folds
zc - closes fold
zm - increases auto fold depth
zr - reduces auto fold depth

And if you ever get annoyed with the folds, use

: set foldmethod=syntax

or press:

zR

to make them all go away.

:set foldmethod=syntax

should fold all functions and other blocks automatically, if you have syntax file for your language.

yes, it is bound to the 'z' key, e.g. zO opens all folds. see ":help fold" in vim for more information. You can do folding according to very simple rules, like indentation, or according to the code syntax.
