With the file extension CAL calendar files of the calendar creator are marked. The Calender Creator is a program for creating your own calendars. He also offers many templates, styles and pictures. Of course, you can also use your own pictures.
A Cal file contains all the project data for a calendar, such as format, style, images or time. The CAL format is proprietary and represents the native file format of the MS-DOS version of the calendar software. Later versions use file extensions such as cce, ce3, ce5 and currently bcc.
CAL files can also be processed by other Broderbund products. These products also have a calendar function and can import CAL files.
