Cannot Delete General Log File for MySQL - Shows Still Open In Workbench

I am attempting to delete the General Log File for MySQL, but I get the message

'The action can't be completed because the file is open in MySQL Workbench.'

I don't see the log file open, and I have turned it off via query in MySQL Workbench. Is there another way to ensure that the log is not open in Workbench?

Thanks

Solution

Thanks - When I ran Task Manager, there were no applications running, so I installed Process Explorer and that found the running instance of Workbench. I killed it, and now I have been able to delete the log file
