How to deal with local disk C suddenly enlarged

Hi all. I want to ask why when I built the design map on my local C disk unreal engine suddenly it became big. Does anyone know how to handle it. thanks.

Tro to go ttp the paking setting suder and add the maps you want to ship inthat list. Maybe you need the “BuiltData.uasset” too.
