This log file goes back to 3/19, has grown to 10MB, is in use by the webshieldprovider, and seems to have no control on length or apparent function. What is it and why do I need to keep it? I deleted it anyway, and a new one has started.
Edit: Another log bonus. For Daylight Savings Time the Chest made another copy of all the system files, since the timetags were now an hour later. I felt safe in deleting those too. Don't know whether the earlier time in October will cause a new copy?
