4D Includes an "ASIFONT.FON" file in the root folder of the application next to the application. "ASIFONT.FON" is included for plugins using Altura. In v14 this is mainly for compatibility issues for plugins that may be using it. If removed, plugins will still work and use MS Sans Serif instaed of ASI_System or ASI_mono. If needed or desired it is safe to remove the file but it is also safe practice to see check if the behavior of any plugins were changed without the file..
