The file extension, which is whatever text comes after the last period (.) in a filename tells the system what it is and what should be done with the file.īy default, Windows has dozens of types of file extension associated with specific actions so they can be recognized on double click. Each type of file in Windows needs to be told what it is so the appropriate action can be taken and the file can be opened or launched.
