No. Brace expansion happens whether the files are there or not. This is
why you can do things like
% cp file{,.bak}
and have it work, even if file.bak does not exist. With the extglob
shell option, the +() will only expand if it matches any portion.
zsh bash
% setopt extendedglob $ shopt -s extglob
% echo foo* $ echo foo*
foo.html foo.html
% echo foo.(html|css|js) $ echo foo.+(html|css|js)
foo.html foo.html
% echo foo.{html,css,js} $ echo foo.{html,css,js}
foo.html foo.css foo.js foo.html foo.css foo.js
