[solved] What is the Difference between Popup Menus and Virtual Folders

Sorry but I'm a bit confused, What is the Difference between Popup Menus and Virtual Folders? When I look at webpage at http://www.truelaunchbar.com/features.html#id883 it seems to imply that they are different.

Visually there are no differences, both are the popup menus. Difference is in the content of regular menu and virtual folders.

Regular menu shows the shortcuts from the corresponding folder in the internal toolbar folder. And this folder is created when you create menu.

The Virtual Folder shows the content of selected external folder (Computer, Documents, Printers etc.). The virtual folder works like a Windows Explorer, but inside TLB menu.

Thanks!
