Change log file location

I have moved all my data folders & files to another drive and it shouldn’t be difficult to change a file location. Yet I see nothing in the settings (or even the registry or the few INI and XML files I found?) that refers to the log file location. Do I really have to do a repair or uninstall/reinstall for something this simple? Does anyone know a way to do this? Please?

How did you move them and why?
