NERDTree should follow vim directory about nerdtree HOT 4 CLOSED

Just use a mapping like the following to execute NERDTree for the current file's directory:
noremap n. :execute "NERDTree ".expand("%:p:h")

I have created some more "n"-prefixed mappings here:

noremap <Leader>n :NERDTree<space>
noremap <Leader>nb :NERDTreeFromBookmark<space>
noremap <Leader>nn :NERDTreeToggle<cr>
noremap <Leader>no :NERDTreeToggle<space>
noremap <Leader>nf :NERDTreeFind<cr>
noremap <Leader>nc :NERDTreeClose<cr>

In your case, you would have to use some autocommand to change to the current directory, if that's what you want really.

At the moment I am using a solution borrowed from Janus:

https://github.com/carlhuda/janus

It simply rewrites the default commands for cd and a few other commands:

" Define the NERDTree-aware aliases
call s:DefineCommand("cd", "ChangeDirectory")
call s:DefineCommand("touch", "Touch")
call s:DefineCommand("rm", "Remove")
call s:DefineCommand("e", "Edit")
call s:DefineCommand("mkdir", "Mkdir")

and the new methods will change the directory of the nerdetree accordingly.

You can use the shortcut ZyX gave in Stackoverflow.

nnoremap \f :NERDTree .<CR>

I don't see any autocmd in the list that would respond to a changing directory, but the quick \f keypress will give you the tree you want.
