I deleted the exported zip file that was placed in my exported templates folder and of course it still shows in Visual Studio\'s \"Add New Project\" dialog. I expected that but
Try looking under %userprofile%\Application Data\Microsoft\VisualStudio\10.0\ProjectTemplatesCache. This is where the unzipped cache of the template would usually be stored. If it isn't there, try searching for a folder named ProjectTemplatesCache anywhere in your user data directory.
