You can move the files using different storage methods available. For example, if the computer is equipped with a CD/DVD-RW you could use a CD/DVD to burn the data on this type of storage and transfer it to other computer. An easier way is by using a USB storage device. A portable USB stick or HDD is the best in these cases. Simply connect the USB to the original computer, copy the files on it and then plug it to the new computer and copy the files back and that's it. You can buy cheap USB sticks from Ebay, Amazon or from your local IT store.
