There is some program running that is creating .tmp files in my \Windows\Temp folder and filling up the hard drive. How can I determine what program is doing that? Is there some utility that I can run that tells me what program is writing to a files on disk?

Sysinternals filemon will be the solution.


Update : I think it is replaced by Process Monitor.

Process Monitor

Yes, it'd been replaced and that's what the tool will tell you too :-) – Joey Aug 8 '09 at 0:23

If it really bothers you then create either a scheduled or startup task that runs:

del c:\windows\temp\*.* /F /Q /S

You may also want to do the same for \Local Settings\Temp
