Can i transfer files from a harddisk to a laptop via annother laptop using lan c

In answer to your headline question -- though part of it's missing-- yes you can transfer files via network cable in principle but you need to supply the missing details before anyone can give you a proper answer.

As for "Hello, monkey". Well, hello monkey back at you.

While possible (need a crossover cable) it is still easier to use a USB storage device (ie external hard-drive, or thumb drive).
