For what are the many *.sqlite files in "Tasks" sub folder? How to auto-delete?

[thoste]

As I found out there are many *.sqlite files created in "Tasks" sub folder.
Whats the purpose of them?

How can I let CH auto-delete them as soon as they are not necessary any more?

Those are information for tasks that you see in CH. When you clear the list of tasks, those files should be deleted - either immediately, or on next restart if it was not possible to do it immediately.
You could try "Automatically remove finished tasks" to remove finished jobs immediately after they are finished.
