Combine CSS and JS files from plugins

I want to combine all my CSS and JS files.
Given the fact that I use different plugins I don’t see a way to do this manually because after an update of the plugin I have to start all over.

So I did some Googling but didn’t find a satisfying answer to my problem.

Can anybody tell me how to combine all my CSS and JS files?
I have no experience with this so… kinda stuck.

Try using Autoptimize WordPress plugin or W3 Total Cache WordPress plugin, with W3 Total cache enable minify option. They both support combining and minifying all enqueued Scripts (JS) and Stylesheet (CSS)
