The best way I have found to transfer files like that is over ethernet from laptop to desktop. People say you need a crossover cable but you don't.
plug the ethernet in the laptop (computer B ) and the desktop (computer A).
Go on computer A and go to network connections and change the ip of the ethernet card to something like this:
And do the same thing on computer B's settings but give it another ip and make the default gateway the ip of computer A:
Then, go on to comuter A and right click the folder you want to transfer and go to properties, sharing, and share it.
On computer B, go into explorer and in the address bar put in the ip of computer a with this behind it // so for this example it would be //10.0.0.1
It will ask for the name and password of computer A and you put it in and then you are looking inside that folder on compuiter A. Copy everything you want and paste it on computer B.
If your laptops ethernet card is the same speed as mine 20-30gb is a 20-25 minute wait. Hope it works for you.
