Seriously, this is the first time I heard that one. Maybe they don't mention the location of the log files in the Quick Start Dumbo User Guide, but I don't see how they're going to keep it hidden from a good file manager.

That doesn't mean, of course, that fritzing around with those funnily-named files is necessarily the smartest thing to do. Unless you happen to like phone-shaped doorstoppers, that is...
