Less verbose not always good. :-) And your expression allowed either -
or _, [\w | -] allows only -, which is your intent?

Why? Why limit the length of the extension? Perhaps a minimum length
{3,} to make it a minimum of 3, but why a max of 4? It's been a long
time since we were limited to 8.3 filenames.
