Hey this is from a website I found:

These files are 'orphaned files' usually generated when your pc is shutdown
improperly or a particular process is aborted. It can be any process it is
not specific to one service or process. Obviously something is not shutting
down correctly but as to what is anyone's guess. I certainly haven't got any
instances of the file on my pc - well not that I can see at the time of
writing this post anyway.

When you have a file like this, copy the file name and to a google search on
it.
 
They are created when you open the computer management program and look at
the performace tab on the left hand side. Other processes might create them
as well I don't know but performace logs and alerts definately does.

Click to expand...

I believe they're some sort of Windows record of programs executed,
theoretically for optimization purposes, but I'm not certain.

They should be deletable the next time you reboot. I've seen these
fairly often, because I have a bootup script that shows the contents
of TEMP and asks permission to delete.
 
OK, thanks.. will let them be..

Those are "performance" files, and can be created by several
different things. You can delete any of them except the one with
a time/date that covers the current session of your computer
you're on. I don't undersand their use, only that they're part
of the OS and used by the OS. They're apparently not always
necessary as I've seen third party programs to stop them from
being created, but ... why go to the bother, IMO? They're all
deleted anyway when you do a cleanup, except for the current one
that's in use. Oops! I meant, they're -supposed- to be deleted
(the old ones).
Some people even write bootup scripts to delete anything there
at boot time, which would help control the buildup of old ones,
but ... doesn't seem worth the effort to bother with, to me at
least.
They're supposed to be deleted during shutdown but various
things can happen that prevent that, and thus extra ones are left
littering the folder.
So, delete what you can, don't worry about the ones you can't
delete. They don't cause any problems that I ever heard of.

Here's a thread about them:

They're performance data logging files. Seems to me they shouldn't be
happening... The NT executive services might be using Performance
Monitoring, but I think usually you have to turn Perfmon on before these
files show up or invoke perfmon so that it can create the files to begin
with. And even then if I remember correctly they can usually be deleted.
