What is "ini"
The INI file format is an informal standard for configuration files for some platforms or software. INI files are text files simple with a basic structure composed of "sections" and "properties.
Format:
Keys (properties)
The basic element contained in an INI file is the key or property. Every key has a name and a value, delimited by an equal sign(=). The name appears to the left of the equal sign.
name=value
Sections
Keys can be grouped into arbitrarily named sections. The section name appears in a row, between brackets ([ and ]). All keys after the section declaration are associated with that section. There is no explicit "section end" delimiter. They end in the next section statement or at the end of the file and cannot be nested.
[section] a=a b=b
Commentary
Semicolon(;) indicates the beginning of a comment. Comments continue to the end of the line. Anything between the point and comma and the end of the line is ignored.
