Cudnn8 takes more than 7gb

Hi, my Ubuntu partion size is limited, and since I upgraded to cuda 11 and cudnn8, they are taking too much space. I just realized after extracting cudnn .tar, it takes 7gb. It is more than cuda-toolkt itself. Is there a way to decrease this size? Would using .deb version help? But deb files are for 18.04 and 16.04, so I haven’t tried it on my 20.04 system. Thank you.

Edit: The problem has solved. It looks like, when we copy the files, we lose symbolic links, so the library was more than what it should be
