            By default file.log is rolled to file.log.yyyy-MM-dd or file.log.curSizeRollBackup.
            However, under Windows the new file name will loose any program associations as the
            extension is changed. Optionally file.log can be renamed to file.yyyy-MM-dd.log or
            file.curSizeRollBackup.log to maintain any program associations.
