Use this command to open an existing QuickFill database. A QuickFill database consists of eleven files which have names of the form "xxxxx_Hnn.qfdat" where "xxxxx" is a name of your own choosing (but is often QFWDB) and "nn" represents the numbers 01 through 13. You only need to open any one of these files. QuickFill will automatically open the other ten files.
You can create a new database with the New database command.
