Transfer data from Windows to OS X
Windows stores all of the users files in C:\Users (for windows Vista and up) or C:\Documents and Settings (for Windows XP).  Inside that folder you'll see all of the user accounts for that Windows computer.  Copy the user you want over to a flash drive or external hard drive then plug it into your laptop.  On your Mac, use the Migration Assistant to finish the transfer or just copy and paste the files yourself.
