Introduction

INI is a configuration file with a fixed standard format
Base elements are keys or properties
Each key consists of a name and a value, separated by an equal sign (=)
key name is displayed to the left side of the equals sign
Equal sign (=) and semicolon (;) are reserved characters
INI configuration method comes from the MS-DOS operating system

Now an informal standard for many configurations, other operating systems may use .conf or .cfg as a suffix
