Guild Wars 2

I only have a 4GB USB. Is it possible to copy and paste the game in chunks to a new PC?

Technically yes. You have to find a .zip program that can do ‘volumes’ and splitting, search for .zip splitting and you’ll find plenty. Then you just tell the program to split the archive into 3.9gb chunks(cause you don’t really have 4gb of space to use) and copy them one at a time to the other computer, then use the program to extract the chunks to the new gw2 folder.

You can use http://hjsplit.org/ to split and rejoin but why not do it over the next work?
