UE4 Engine Size Post Update

So I have been causally working with ue4 for a long time now, first with blueprints and now full scale in c++. I have been working in 4.19 for the whole time with c++ and just now updated to the most current. And now, well I thought I had a ssd to use, but this update has proven me otherwise as the engine online takes up nearly 100 gigs. I have read that sometimes that updating can hord data, any ideas on what I should do to help? There must be something I am missing
