what is a root menu?

The "root folder" or "root directory" is the storage area immediately off the drive letter when viewed in Windows Explorer (NOT "Internet Explorer"!). All other folders (directories) are nested inside the root.

In this image since Drive D: is selected on the left side of the window, the contents of D:'s root directory are displayed on the right -- the sub-directories "Acronis, DVD1, DVD2" etc.
