This may sounds weird or strange... But, I actually installed Wotlk in my computer using a CD and I used a USB disk to import it to my other computer (who can't read CD but is better, graphically and can run WoW), the problem is that my USB disk is 2 Go and one file, Lichking.mpq, have a size bigger than 2 Go, so my question is, is there a way to cut the MPQ into 2 smaller MPQs, import them one by one, and then merge them again ?
