Thank you for posting your question in the Microsoft Community Forums.
Based on the information, you are trying to find out the purpose of the "PrintHood" folder in Windows Vista Users folder.
"Printhood" Stores the path to the folder containing shortcuts to printers that you have added to the computer.
These folders are what are known as a junction. Junctions work like shortcuts, but in Vista's case look like regular folders with an arrow. The purpose of a junction is to redirect programs that access them to their Windows
Vista equivalent. Since junctions aren't really folders, it is not possible to access them, and any attempt to do so will give you an "Access Denied" error.
