Initialization files are configuration files used by software applications to set up their environment and parameters before they run. These files typically contain settings such as user preferences, system paths, and other options that dictate how the application behaves. They help ensure that the software operates correctly and efficiently according to the user's needs. Commonly found in various operating systems and applications, initialization files often have specific formats, such as INI, JSON, or XML. They are usually loaded at the start of the program, allowing for a customized experience without requiring users to manually adjust settings each time they launch the application.
