INI file
Updated: 08/02/2020 by Computer Hope
An INI file is an initialization file for software to store configuration information about the computer or program. Important .ini files such as the system.ini and win.ini are needed for earlier Microsoft Windows to operate properly.
Today, .ini files' functionality in Microsoft Windows and its programs are mostly replaced by the Windows registry. However, files such as the desktop.ini file still exist in many versions of Windows today.
