VIM has stopped using my _vimrc and I can't figure out where it is getting set?

Question

My _vimrc looks like this

set nocompatible
source $VIMRUNTIME/vimrc_example.vim
colorscheme pablo
set backup=~/vimfiles/backup
set directory=~/vimfiles/tmp

set diffexpr=MyDiff()
function MyDiff()
  let opt = '-a --binary '
  if &diffopt =~ 'icase' | let opt = opt . '-i ' | endif
  if &diffopt =~ 'iwhite' | let opt = opt . '-b ' | endif
  let arg1 = v:fname_in
  if arg1 =~ ' ' | let arg1 = '"' . arg1 . '"' | endif
  let arg2 = v:fname_new
  if arg2 =~ ' ' | let arg2 = '"' . arg2 . '"' | endif
  let arg3 = v:fname_out
  if arg3 =~ ' ' | let arg3 = '"' . arg3 . '"' | endif
  let eq = ''
  if $VIMRUNTIME =~ ' '
    if &sh =~ '\ ' . arg3 . eq
endfunction

however I believe it is using settings that would look like this

set nocompatible
source $VIMRUNTIME/vimrc_example.vim
source $VIMRUNTIME/mswin.vim
behave mswin

set diffexpr=MyDiff()
function MyDiff()
  let opt = '-a --binary '
  if &diffopt =~ 'icase' | let opt = opt . '-i ' | endif
  if &diffopt =~ 'iwhite' | let opt = opt . '-b ' | endif
  let arg1 = v:fname_in
  if arg1 =~ ' ' | let arg1 = '"' . arg1 . '"' | endif
  let arg2 = v:fname_new
  if arg2 =~ ' ' | let arg2 = '"' . arg2 . '"' | endif
  let arg3 = v:fname_out
  if arg3 =~ ' ' | let arg3 = '"' . arg3 . '"' | endif
  let eq = ''
  if $VIMRUNTIME =~ ' '
    if &sh =~ '\ ' . arg3 . eq
endfunctio

The problem with this is

A) I liked my colorscheme it was there thanks to your help

B) I don't want to use the mswin configurations it messes me up especially the ctrl-z and ctrl-v doing things I don't like. I prefer having ctrl-v go to visual mode like makes sense.

C) I would like to have a temp directory and backup set up for vim. (to be honest I'm not sure if I'm doing this part right.

Answer 1

In VIM, type :version, and that'll at least show you the order that the *vimrc files are being loaded.

As for c), the set directory bit determines where VIM puts its swap files. To specify where the acutal backups go, use :set backupdir
