Years ago I reported this bug that never was fixed from what I can tell.

These temp files can be manually deleted.
I'm running ME and NAV 2005. When I try to do a comprehensive scan NAV somehow finds about 100,000 temporary files that I can't locate on my system. This results in the scan process taking about an hour and a half plus I don't want any temporary files maintained anyway.
I am diligent about deleting temporary files and befuddled by where these may be hiding. Any ideas on how to address this problem.
