The Copy as Path context menu option is a built-in option in Vista. You will not see the Copy as Path option by simply right clicking a folder or file because it is included in the hidden context menu.
To copy the file or folder path, press the SHIFT key, and right-click on a file or folder. Click the Copy as Path option from the context menu. The object’s (file or folder) full path is now copied to the Clipboard allowing you to paste into a document, email, etc.
