Gvim/Vim open file without source .vimrc

We usually customized vim by editing .vimrc file or install some vim plugins under .vim directory.
But sometime vim plugins slow down gvim while opening huge file, in that case we can open that specific file without sourcing .vimrc file ,also not loading plugin
Vim how to open files without souring .vimrc file
gvim -u NONE myfile
-u NONEwill skill loading .vimrc ,also will not load plugins
If you are using .gvimrc instead for gvim , you can use option -U
gvim -U NONE myfile
Or
gvim -u NORC myfile
-u NORCwill ignore vimrc file but NOT skill plugins
