Steps to reproduce the issue

Create a new action log with the default settings and run it a few times. Then check the administrator/logs folder

Expected result

A log file

Actual result

No log file

Additional comments

Either its a bug or the field name needs clarification

When I saw this option I assumed (perhaps wrongly) that all scheduled tasks would be logged into a single log file

And I only needed to set individual log files if I wanted to keep the logs for each action separate
