I'm setting the below variables in my vimrc to control how windows get split when I bring up the file explorer plugin for vim. But it appears these variables are not being read because they have no effect on how the file explorer window is displayed. I'm new to vim. I know the vimrc file is being read because I can make other setting changes and they get picked up but these don't work. What am I'm missing?
let g:explWinSize=10
let g:explSplitBelow=1
let g:explDetailedHelp=0
