FAQ

ROZ to STP Conversion

What are ROZ files?

ROZ is the project file of aSc TimeTables, a school timetabling program developed by aSc Applied Software Consultants. A file of this type holds the complete data of one school schedule: the school details, days and periods, teachers, classes, subjects, rooms, students, and the lessons placed in the weekly grid with their constraints. The program builds a timetable automatically from this data and checks for clashes, for example when a teacher or room is not free at a given time. A ROZ file is the working source of the schedule, so schools keep it for later changes, and it can be used to import the timetable into other school management systems. The program is available for Windows and Mac.
