FileName.Ext
- saving to a text file of a given name. From Starting with the V21.1 version, it is possible to use Windows environment variables. Usage example: "% userprofile%\Monitoring\logon.txt".

The file size is controlled by the maxMax_logLog_size Size parameter that is described in the the Special Settings chapter.
