planckscale writes "After spending another hour deleting .tmp files from a bloated XP machine I started to wonder, is the .tmp file necessary when coding an application on the MS platform? Why do so many apps produce .tmp files and is it just because of bad coding or does the use of them dramatically speed up an app? Don't coders use dev/null to reduce them in linux? I can understand the use of them in case an app crashes for recovery purposes, but why don't more apps have the capacity to delete their own .tmp files once they are done with them? Is it too much to ask to at least have the option when closing an app to delete your temp files?"
