Ark Dev kit and Unreal are way to big to download

ark Dev kit and unreal are way to big for me to download they say i need 120 gig of free storage why when the game folder is already 84 gig . all i wanted to do was make a Factory Resource miner similar to one in Ark Comes Alive not any dino’s just a miner for all resources with stacks of 10000 and 1000 item slots. (it was not meant to craft anything) so i have given up as i dont have the space on my system.

Ark has a lot of assets. The main game, The Center and all the Scorched Earth assets are included with the devkit. In order to properly mod it you need access to all those assets. Hence the large download.
