Operation log is composed of an outputting log file, its generation file (backup file) and a generation management file
saving the management information of generation file. An operation log is created on the log file saving directory
(installation directory\etc\log). A generation file has a structure that holds backup of a log file one by one and it is
created to a maximum of 99 files. However, if the number of generation files exceeds the maximum, the oldest file will
be overwritten.
These file changes and name changes are performed automatically, and the user does not need to pay attention.
Example: When 17 generation files have been created by the operation log.
