Windows Explorer officially debuted with Windows 95, but a similar tool existed in earlier versions of Windows as well.
In Windows 3.1, which launched in 1992, the tool had been known as File Manager. It was pretty limited in its scope, allowing users to drag and drop, rename, cut, paste, and delete files, along with some other menial tasks.
Microsoft's Windows 8 purports to be a PC operating system for every device. But a PC experience may no longer be necessary.
