That kind of attitude leads to user blaming. I have fond memories of the workgroup network scan freezing my computer for extended durations in the xp days
Or just download a large file, choose save as on a drive other than the C drive because it is too big, and watch IE proceed to fill up the temp dir on the C drive, completely ignoring the fact you asked to save on another drive.
Or if you had enough space, still waste minutes copying the deleting the file...
that 'save to temp-dir first and copy later' behavior is so frustrating because it's inconsistently applied and not easily avoided, yet somewhat incomprehensible to the average user.
