问题:

I tried to change the NERDTree root with

:BookmarkToRoot <bookmark>

command and with C letter but when I close vim and open vim the root is not changed.
Do you know how to change the root forever?

You could try something like:

nnoremap <leader>n :NERDTree /path/to/folder<CR>

I have this in my .vimrc:

set autochdir
let NERDTreeChDirMode=2
nnoremap <leader>n :NERDTree .<CR>

so that NERDTree always opens in the current folder.

With the 1st line, the working directory is always the one where the active buffer is located.

With the 2nd line, I make sure the working directory is set correctly.

With the 3rd line, I hit <leader>n to open NERDTree.

As i don't want vim to change directories automatically, i just use:

com! -nargs=1 -complete=dir Ncd NERDTree | cd <args> |NERDTreeCWD

so you can just do a ":Ncd path/you/like/" with path completion.
