The most recent filename extension database

The filename extension is a set of characters preceded by a dot, which usually constitutes the suffix of the filename. In Windows, filename extensions are associated with file types, and file type refers to the application used for opening it. In the filename myvideo.avi, the extension is avi. It tells Windows that this is a video file that can be opened by programs associated with that extension, such as Windows Media Player.

By default, Windows Explorer hides filename extensions in Windows 7 and earlier versions of Windows.
