Where do I find the combined/minified files

I’m running speed tests on my site with GTMetrix and tools.pingdom.com to see how much minifying the JS and CSS on the site improves the voerall performance.

I still see all of the separate JS and CSS files being loaded… Shouldnt only 1 JS and 1 CSS file get loaded if they are being minified and combined?

Or am I misunderstanding what the plugin does?
