Just one of many articles out there. Tim Fisher is pretty dependable though. I can't think of too many temp files you can't delete. But, you can delete those. They were likely made "temporarily" during an install of an application or Windows doing its thing. Of course, you can't go wrong with an app like CCleaner, which will clean anything you want and tell you how much space you freed up.
