VIMRC not working

Instead of using the user vimrc file: $HOME_vimrc and user gvimrc file: $HOME_gvimrc I used 2nd user vimrc file: $HOME\vimfiles\vimrc and 2nd user gvimrc file: $HOME\vimfiles\gvimrc

• working: $HOME\vimfiles\vimrc
• not working: $HOME/_vimrc

   system vimrc file: "$VIM\vimrc"
     user vimrc file: "$HOME\_vimrc"
 2nd user vimrc file: "$HOME\vimfiles\vimrc"
 3rd user vimrc file: "$VIM\_vimrc"
      user exrc file: "$HOME\_exrc"
  2nd user exrc file: "$VIM\_exrc"
       defaults file: "$VIMRUNTIME\defaults.vim"
