Transfer files/folder to new computer?

[Budder]

Hey guys!
So I upgraded to a better newer game computer and was wondering what the best way is to transfer the game to that machine would be?
Could I just send the game folder to a thumb drive and then put that folder on the new computer?
Do I need to extract the files or what is the best way to do this?
Any easy advice would be apriciated greatly.
Thank you!
