The preinstalled Smart Connect software allows you to use an i.LINK®
cable (optional) to connect your VAIO Z505 SuperSlim Pro notebook to
another VAIO computer that also has Smart Connect. You can then use
one computer to copy, delete, and edit files on the other computer. You
can also print from a printer attached to either computer. See the Smart
Connect online help for more information.
