File extensions are used by Windows operating system to specify what kind of information is stored in the file. Every file in Windows OS needs to have file extension and file extensions are used by Windows to determine which application it should use to open the file. Every application installed on Windows OS places information about which extensions it could open into the Windows registry and Windows uses this information to determine which application it should launch when user double-clicks on the file. If application which can open ONE file is not installed, then Windows will show ‘Windows can’t open ONE file’ message and buttons to either select an application on the computer which can open the file or to search the web for the application which can open ONE file.
