Evermotion Mesh (FBX) size is really really huge

Development Character & Animation

Hello all!

I bought time ago some models from Evermotion pack. The model of a broken plane, for example, goes up to 2Gb and I really need to make it much smaller than that.
I have tried to open it with Blender but gives an error so I cant modify it.

My question is, how can I reduce drastically that model of 2Gb?
Which apps would you use?

Thank you

when you import to UE4, (does it import?) if you check the “combine meshes” button, and re-export the FBX, does the size change?
