I am trying to update the ARK Dev KIT.
It is currently installed on its own 120GB partition, a new installation from 2 weeks ago, no projects yet created so plenty of free space.
When I launch the Epic Games Launcher and choose “Update” it tells me "Insufficient storage available at “D:\ARKDevKit”. 63GB required. Available free space 49GB.
How big is this update? Is it going to do a full re-download, I would have thought the launcher should do a differential download?
