I'm trying to install NERDTree (the Vim plugin) on Windows 7. I created a .vim directory on my user folder (C:/Users/Username) and extracted the plugin there. I've run :helptags ~.vim\doc and :helptags [full-path]. Closed and reopened Vim.
But when I try:
:NERDTree
the editor says:
E492: Not an editor command: NERDTree
How should I do it?
