File Explorer
Windows Explorer is the application used in modern versions of Microsoft Windows for displaying file and directory listings and information. Windows Explorer, which originally was completely distinct from the Internet Explorer web browser, debuted in Windows 95 as a replacement to the older Windows Program Manager. In addition to file management, Windows Explorer deals with functions tied to the Windows "Start" menu (Run, Settings, Documents, Programs). Windows Explorer also controls the Windows searching function and File Type associations (extensions).
With the release of Windows 98, Windows Explorer became based on Internet Explorer technology, most notably with the addition of navigation arrows for moving between recently visited directories. Many see this as another example of Microsoft's anti-competitive tactics of tying their software applications into the operating system. In Windows Me, the navigation arrows are smaller than in Windows 98.
In Windows XP, Windows Explorer is significantly different than in previous Windows versions; by default, the Luna interface is used but can be turned off if desired.
