ifc model larger than initial after export

[Anonymous]

Hello community,
I have an ifc model which has the size of ~160mb. After removing some unnecessary elements and exporting, the file size went close to ~300mb. Why did that happen since i expected it to be less than the initial size. Attaching a screenshot of the ifc save options. https://i.gyazo.com/2c0da8b4c446fceafab5abd1b991771f.png

did you check, maybe you are exporting additional attributes such as the Archicad_Properties, Quantities & co?
