Whoaaaaaaaaaaaaahohooooo.
What? I am down to …
Something wrong here.
Hey folks.
I just downloaded and built UE4.22, and I am shocked.
I must have done something terribly wrong, because the last time I built UE4.0, it was only 25 GB.
Please tell me I did something wrong. 
My internet connection got cut, while setup.bat was running. Could it be, files were duplicated? Or is the engine really that enormous?
Do I really need all these files to have a good working experience with the engine, or can I cut this down to at least 25 GB?
