Program information file

A program information file (PIF) defines how a given DOS program should be run in a multi-tasking environment, notably to avoid giving it unnecessary resources which could remain available to other programs. TopView was the originator of PIFs; they were then inherited and extended by DESQview and Microsoft Windows, where they are most often seen. PIFs are seldom used today in software due to the absence of DOS applications.
