Folders Not Displaying in FP2002

This problem is very annoying. For some reason, when I attempt to create a link, many of the folders listed in the Folder List do not show up. I can physically go into those folders either through the use of the Folder List or through Windows Explorer, but some folders simply do not display when I attempt to create a link. Strange and like I said, very annoying. Hope someone can help.\r\r-Lou-
