Faster File Copy

I'm currently using the Dell Vostro laptop which Datacraft gave to us. Last October 2, I transferred all my files from my Asus Laptop to the new one. I was thinking of an efficient way of transferring more than 30GB of files. The issue was not limited to the file size, but also in the number of files to be transferred. If they were just 10 big files, it would be simple, but there were many small files involved. I decided to make a network transfer, since our portable hard drive has only few free space remaining.
