I have no idea how to do this.

I am still massively confused. I've managed to extract a few packs, but i always seem to forget how it's done.

Here's what I know for sure what to do:

I go to Tyler Sontag's link above, click a pack (let's go with Ember, since it's the first pack I played through), and opened the file that appeared below. Once it's open, I'm not sure what to do next. When I right-click it, there's no "extract all" option.
