As of version 4.5, Ranger can log to disk via options set in the
'C:\ProgramData\Silver Bullet Technology\Logging\Ranger\Ranger.ini'
file.
In order to enable logging to disk automatically, ensure the
following values are set in the Ranger.ini [Logging] section:
- AutoLogToDiskEnabled=True
- AutoLogToDiskPath=C:\ProgramData\Silver Bullet Technology\Logging\Logs
You
can customize 'AutoLogToDiskPath' to the directory of your choice. Log
names are auto-generated, based on 'Name' and the date/time.

NOTE:
Ranger does NOT manage log files. The log files will continue to
accumulate as long as the option's enabled. SBT recommends clearing
logs daily.
