JET****.tmp files - What are they?

I'm running Win XP Pro with security through AVG antivirus, Spybot, AdAware, and
Kerio firewall. Recently I have noticed 22 files in my temp directory, of the
form JET****.tmp (eg JET8A3E.tmp etc). If I try to delete them Windows tells me
they are in use, but I'm not aware of any application running. My security
applications don't flag anything.

Are they a problem? If so, how do I fix it? If they're benign, what are they?
Help, please.

They are files connected with the Microsoft JET Engine, used for
databases.

So don't worry about it.

Take a look at Process Explorer from Sysinternals. It will tell you what
program is holding those files open.

I like Process Explorer, but how do you get that information from it?
None of the menu selections seemed relevant when I checked them just
now. And the help index contains nothing beginning with "open" or
"file".

You're looking for file handles. A file handle is the way a program
"handles" a file that it has open. Search for "jet" under file handles
and see what turns up.

Thanks for the reply. I must be missing something obvious, but I
can't find how to display a list of file handles. Can you point out
what I'm missing? (Is this perhaps a recent feature? I've got release
9.25.)

There is no list. Go to the menu bar at the top of the program and
select Find -> Find Handle. Type in "jet" without the quotes and search.
Find the file in question in the list of results.

Thanks! That, I understand.

I'll drop the author a note suggesting an update to the help file.
He's amazingly responsive, considering this is free software.

And just to review, for anyone who doesn't have it -- Process
Explorer is at
http://www.sysinternals.com/Processe...Utilities.html
along with a lot of other useful utilities including Autoruns.

Thank you both for your response. Turns out, when I recently installed Roxio
Easy Media Creator 8, it unilaterally concluded I wanted some part of it running
at all times. The temp files are owned by RoxMediaDB.exe. What is particularly
annoying is that I use PC Magazine's Startup Cop for Win XP to keep tabs on that
sort of thing - and it doesn't show in the list!
