Storage issue

I am using Twinmotion for architecture rendering. But I have a big problem with the storage, “Epic Games” folder is 71.9 G, is it normal ? I didn’t expect that the software can be so huge because my PC only has 512 G totally. Would you give some advices for deleting some files ?

For instance, while update Twinmotion 2020 to 2021, can I delete the 2020 version?

UE is huge, there’s no way around it. You can trim down the bloat a little by deleting iOS and Android support, which could save 10G. You have to go in the Epic launcher, and find the UE item, and go to it’s options menu.

Never used, Twinmotion, can’t answer that.
