How to transfering L2 to laptop?

Hello, i own the game on my PC but i want to transfer it to my laptop. I transfer all the files into the laptop directory, but the launcher start to download it again one by one.



My connection is not so fast, so anyone know any solution for this problem? Or im going to need to download the game again on the laptop.



At this moment im downloading it, but i think i will get it faster by transfering by any way.
