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
My OS Windows 8.1 and I use Visual Studio 2013.
Here is the path of Custom Templates;
%userprofile%\AppData\Roaming\Microsoft\VisualStudio\12.0\ProjectTemplatesCache
For this case, my path of custom templates like;
C:\Users\xxxxx\AppData\Roaming\Microsoft\VisualStudio\12.0\ProjectTemplatesCache
