[Description] Fully qualified path to the file where each event log is stored. This enables Event Viewer and other applications to find the log files. This value is of type REG_SZ or REG_EXPAND_SZ. This value is optional. If the value is not specified, it defaults to %SystemRoot%\system32\winevt\logs\ followed by a file name that is based on the event log registry key name. The specific event log file path should be set using the command line utility wevtutil.exe or by using the EvtSetChannelConfigProperty function with EvtChannelLoggingConfigLogFilePath passed into the PropertyId parameter. If a specific file is set, make sure that the event log service has full permissions on the file. This value needs to be a valid file name for a file that is located on a local directory (not a remote computer, not a DOS device, not a floppy, and not a pipe). If the file setting is wrong, an event is fired in the System event log when the event log service starts. Do not use environment variables, in the path to the file, that cannot be expanded in the context of the event log service. Windows Server 2003 and Windows XP/2000: This value defaults to %SystemRoot%\system32\config\ followed by a file name that is based on the event log registry key name. If the File setting is set to an invalid value, the log will either not be initialized properly, or all requests will silently go to the default log (Application). [Registry value]
