Note: Use TCustomIniFile as a base class when defining components that access ini files. Ini files are text files that are divided into sections with variable assignments in each section. TCustomIniFile introduces properties and methods to handle storage and retrieval of application-specific information and settings in a standard ini file.

Note: On Windows, TCustomIniFile is also the base class for TRegistryIniFile, which allows applications that use both ini files and the system registry to handle both media in a unified manner. This differs from the features of TRegistry, which corresponds more directly to Windows system registry native semantics.
