Re: Efficiency?? Ha ha ha ha….
The problem is that some developers, including Microsoft itself, actually dump essential installation files in a temp folder.
So that sometime down the line, if you've not unreasonably emptied the very oldest files out of a space hogging temp folder, when you ask a Microsoft installer .msi to add in a component that you'd previously not installed it will throw up a message demanding you tell it where to find a strangely named file that is nowhere to be found on your hdd. Because it was in a f***** temp folder!!!
