How to save level

Hi,

I just started UE4 yesterday and am going through those tutorials now, got to the level creation tutorial #6 and try to save the scene, then “Save level as” window pops out with the Maps folder highlighted. Is that where I should save my scene? Can I open and continue it next time? It doesn’t feel like any other software saving process. Please help. What’s the file extension?

Thank you for your quick response, . I got it, can leave now. It’s a bit strange, tho, maybe need more time to get used to.
