Tmeminifile and Tinifile

In the Inifiles unit, there are three three main operations classes Tcustominifile, Tmeminifile, and tinifile that read the INI file, which, under the Windows System compilation, Tcustominifile are the base classes of Tmeminifile and Tinifile, respectively, The only difference between the two operation classes, Tmeminifile and Tinifile, in the Windows system is that the storage of tmeninifile costs is larger than tinifile. There are several important ways in which tcustominifile
