Easy to fix. Change the "-e file" to a " -f file && -o file ":

alias EnterDir 'if ( -f "$thisdir/$CDENTER" && -o "$thisdir/$CDENTER" ) source $thisdir/$CDENTER'
alias ExitDir  'if ( -f "$thisdir/$CDEXIT" && -o "$thisdir/$CDEXIT" ) source $thisdir/$CDEXIT'


As long as the file isn't group or world writable, that is.
