INI stands for Initialization file, a file format abbreviation.

Plain-text configuration file divided into sections in square brackets, each holding key=value settings. Windows programs, games and some Linux tools still use INI files for settings.

Example: Change the resolution in the game's settings.ini file if the menu won't open.

Usage notes

Windows 3.x relied on WIN.INI and SYSTEM.INI for system settings until Windows 95 moved most configuration into the registry. INI files remain popular because people can read and edit them easily. Hidden desktop.ini files customize how individual folders display in Windows. The format has no single official specification, so details such as comment characters vary.
