What is the Download size of the Unreal Editor?

It’s around 20GB after installing, probably a bit more if you want all content examples and whatnot. You get a much more complete feature set. 20GB was a lot 10 years ago, maybe.

What is the size of the Engine ? I downloaded it Shows as 6.8 Gb. Why is the size soo big as compared to unity. It is around 10 times That of Unity
