No, it 'don't'
As I understand it, apps do not write or delete files in
OS X. That is a service reserved by the OS & provided to the apps on demand,
so if the temp files aren't being released it suggests that some maintenance
may be in order. Since you haven't stated your exact update levels for
Office or OS X I'd suggest you start there. Make sure Office is at 12.2.3 &
that OS X is at 10.5.8 (I believe that's the current level for Leopard).
Additionally, start your Mac from the OS X source disk & run Disk Utility -
Repair Disk [Not 'Repair Disk Permissions']. If any errors are found run the
utility again until it reports no errors. It may also be wise to fetch the
10.5.8 Combo Update from the Apple Downloads site & reapply it.
Keep in mind also that much of the routine disk maintenance doesn't take
place if you don't Quit applications once in a while as well as restart your
Mac. If you leave things running 24/7 those housekeeping chores never get
done & the cumulative effect can get messy.
If you still have the problem please provide additional details about where
the files are stored... Primary HD? Other local HD? Network drive? As well
as any other information you can supply.
