Like many aspects of the new Windows OS, the file and program handling interface has been redesigned to make it more intuitive when used through a mobile device. The redesign has an added bonus of syncing up well with cloud storage systems. The new interface uses sophisticated graphic shortcuts called "tiles" as the primary tools to activate and explore the files on your Windows device.
And that's not the only change in terminology in Windows 8. In addition to "tiles" instead of "directories," applications that used to be called "programs" in the older versions of the OS are now referred to as "apps." Don't worry, your trusty software will work the same. It will just be easier to access and control.
