 ## How can I make sure vim does not open files and other buffers on NerdTree window?
 
 ```vim
-" If previous buffer was NERDTree, go back to it.
-autocmd BufEnter * if bufname('#') =~# "^NERD_tree_" | b# | endif
+" If more than one window and previous buffer was NERDTree, go back to it.
+autocmd BufEnter * if bufname('#') =~# "^NERD_tree_" && winnr('$') > 1 | b# | endif
 ```
