On Schedule uses SSKD files to save schedule data for later use. The format belongs to the program's document files and stores a user's schedule in a form that On Schedule can read.
SSKD is an application-specific format rather than a general-purpose calendar or spreadsheet format. It is intended for use with On Schedule on Microsoft Windows.
Open an SSKD file with On Schedule on Microsoft Windows. Start the program and use its Open command to select the file, or double-click the file if Windows has associated the extension with On Schedule.
Open the file in On Schedule and use any export or printing functions provided by the program. If those options are unavailable, the schedule may need to be recreated in another application.
