Actually there are other ways to get to "show hidden files", too. You can choose Organize>Folder and Search Options (in windows Explorer) or from the start menu you can choose Control Panel>Folder Options ... then it's under the view Tab
Also in windows Explorer, just because it isn't visible doesn't mean you can't get to it. If you type %appdata% (%'s are required) into the top left section that normally displays the path, it will take you directly to ...\AppData\Roaming
