'''FutureOS''' only runs well on a [[CPC6128|CPC6128]] or 6128plus (not CPC464 or 664), because of their support for RAM configuration C3 (essential for the mouse pointer). FutureOS is not compatible with native [[AMSDOS|AMSDOS]] or [[CP/M|CP/M]] programs.
== User Interface File Management Module ==
The user interface file management module (UIalso called Main Screen) of FutureOS presents the user with three fixed sections: an icon section (upper half of screen), a file-name display and selection section (lower half of screen) and a message line (bottom). It appears directly after booting FutureOS, but can also be used from applications for selecting or managing files. The user can browse through directories of discs and hard-disc partitions. A cursor arrow is used to select devices, functions or files; this cursor arrow can be controlled with a nearly all of the pointer based HID devices (joystick, mouse, trackball, light-pen or , grafpad) available for the Grafpad IICPC.
Applications can do call the UI as a subroutine (, and the OK icon user can be used to return to calling the application)via the OK button. The icons are fixed, so the layout remains stable throughout its use.
Files can be viewed on-screen (scroll up and down) or printed. File headers can also be viewed. When typing a text file it is possible to set the number of columns and lines of the window the text is displayed in.
