Even though the program requires that you open an ADIF log file before you starting logging QSOs, the actual QSO information is not stored in the ADIF log file.
The SKCCLogger maintains all of your log data in a SQL database on your PC's disk drive in a file named "LogFileDB.rsd." Whenever you save the log data to the ADIF log file, the data is copied from the SQL database to the ADIF log file.
Updates to the LogFileDB.rsd database file are made immediately as you enter them and the updates are committed to the database file after each change. Upon a normal shutdown of the program, the database contents are written out to the ADIF log file and the database file is deleted.
The following topics in this section will help you understand the relationship between the database file and the ADIF log file.
