1)
Right click on your "My Documents" folder on the desktop and select
"Properties." Click on the "Sharing" tab. Click the two check boxes below
that read "Share this folder on the network" and "Allow users to change my
files." Set a name for the folders.
2)
Be sure you know your desktop computer's name. If you don't, right-click on
"My Computer" and select "Properties" Click on the "Computer Name" tab and
make note of it.
3)
On your laptop, open "My Documents" and then "go up one level." Once there,
right click on "My Documents" and set the location as
"\\DesktopComputerName\DesktopFolderShareName"
You will now be able to access all those documents from your laptop and make
changes. If changes are made when away from your home network, they will
automatically be synchronized when a connection with your home network is
found.
