You can use Windows to copy files between computers that are connected to the same network. If both computers are not connected to the same network, you will not be able to follow these steps and will have to copy files using some sort of removable media that can be read by both computers.
You must know the name of the computer where you want to copy the files. If you don't know this name, ask someone who uses that computer, or go to the other computer yourself and look it up (if you need them, the steps for looking up a computer name are provided in the notes section later in this Help topic).
On the computer that contains the files you want to copy, click the Start button . In the Search box, type two backslashes (\\) followed by the name of the computer to which you want to copy the files (for example, \\mylaptop), and then press ENTER.
Open the folder on the other computer where you want to copy the files or folders.
Open the location on this computer that contains the file or folder you want to copy.
Drag the file or folder you want to copy to the location on the other computer.
Notes
If you are having trouble accessing the other computer or viewing folders on it, you might not have proper sharing permissions.
If you need to find out the name of your own computer, follow these steps:
open System.
Look for the name of your computer under Computer name, domain, and workgroup settings.
since you are using vista, open your help and support and type this "Copy files to another computer"
