I read in the alt.os.windows-xp newgroup it's a leftover file from an aborted SiSoft Sandra disk benchmark, and can be safely deleted ... although that doesn't sound quite right to me. If that was the case, you shouldn't have to delete the same file over and over again. But it's possible, I suppose.
But that was the only thing I could find that was in English, (after using about 7 different search engines) and I don't speak Norwegian, unfortunately.
I don't recall ever seeing such a file in relation to the QoS packet scheduler.
Perhaps it has something to do with power management and Hibernation?
I doubt this is the problem but it might be your virtual RAM file and that it got renamed. You would have to check how much virtual RAM, if any you allow.
I just remember I have a friend who couldn't figure out what a huge file on his HD was. Eventually he realized it was the vast amounts of virtual RAM he had set up.
I crossed the line into insanity so long ago I no longer have any idea which way to go to get further from the line.
