Use this to select the types of lotteries to import from the v6 database: built-in lotteries, custom lotteries, or both built-in and custom lotteries.
Clicking this button opens up a standard file selector. If Lotto Sorcerer v6 is installed on the same computer and user folder as Lotto Sorcerer v9, the file selector will 'land' on the v6 database file by default. Selecting it will immediately launch the importation process.
