No. You didn't follow the instructions and you cloned both pathogen and nerdtree in the wrong directory.
Your configuration (vimrc/plugins/colorschemes/…) should be in your %UserProfile%
directory:
%UserProfile%\vimfiles\
%UserProfile%\_vimrc
On Windows XP:
C:\Documents and Settings\karthikbharadwaj\vimfiles\
C:\Documents and Settings\karthikbharadwaj\_vimrc
On Windows Vista/7/8:
C:\Users\karthikbharadwaj\vimfiles\
C:\Users\karthikbharadwaj\_vimrc
Pathogen's README
is very clear about what to install, where to install it and what lines you must add to your %UserProfile%\_vimrc
; I have no idea where you got that runtime_append_all_bundles()
idea.
The file pathogen.vim
should be in %UserProfile%\vimfiles\autoload\
.
Your %UserProfile%\_vimrc
should look like:
filetype off
execute pathogen#infect()
execute pathogen#helptags()
filetype plugin indent on
syntax on
