myGame.data too heavy

Hello,

I’m trying to upload a small UE4 game on itch.io for browser in HTML5.

But itch.io have a maximum singular file’s size equal to 100Mb.

I noticed that all the assets are in 1 file called myGame.data = 350 mB. when I create a project without asset, myGame.dat = 70mB.

I would like to know if it’s possible to split myGame.data so I can have files under 100Mb
