I thought I'd answered this one recently, but I guess I didn't.

TempOptilnnnn files are created by SIM TuneUp. It's not a virus, it's not a
bug (maybe a misfeature), it's not a problem. 

If you have a locked file that is fragmented, when TuneUp tries to make it
contiguous it does so by creating a temporary file and copying the current
file to it. It then deletes the old file and renames it -- this way, if
something happens during the process the old file isn't destroyed.
Unfortunately, if the file is locked, the attempt to delete it fails and the
other copy of the file is left around.

Easy answer: unlock any file that TuneUp says it can't defragment in the log
(you do read the logs, don't you?) and run TuneUp again. Then lock it again.

One strange note on this: TuneUp can't defragment files that are locked, but
it will happily relocate locked files to optimize disk space if they're
contiguous. The former is evidently done through the HFS filesystem calls
which pay attention to the locked bit, and the latter goes around the OS to
physically move stuff around.

I regret to announce that--though, as I said, eleventy-one years is far too
short a time to spend among you--this is the end. I am going. Good-bye.
