The NerdTree is a vim plugin that enables us to explore files within vim.
Installation
To install NERDTree you can use Vundle with adding this to your .vimrc:
Plugin 'scrooloose/nerdtree'
Usage
All you need to do is either use vim command :NERDTree or map vim-command with Ctrl+n (or other combination):
nmap <C-n> :NERDTreeToggle<CR>
To learn some of the NERDTree key-combinations check the "?" sign at NERDTree, here is what you will find:
