Dell server shows files with ext ".ctm" maxing out the C: drive.

[MrPederman]

My Dell Server, running Windows 2000, is used for Nortel Symposium Web Client (a telecommunications application), It shows drive C: running out of disk space. I can't even open the event log. Files with the extention".CTM" started being created in C:\winnt\temp folder on 10-12-05. They are 6.1 meg each and 12 of them are created each day and so they are filling up the C: drive. I can move the files off the C: drive to temporaraly clear the problem, but what is causing these file to be created automatically? Here is an example file name: "Cel2e1384b8_1704_848.ctm".

Are these files logs that a Windows process started on it's own?

Thanks in advance.

MrPederman,

generally anything in a temp folder is safe to remove.
i usually use scripts, either .bat or .vbs, to routinely clean out such locations.

Thanks for the response. I was unable to remove the ctm files because they say they were in use.

MrPederman,
can you reboot?
if not check your task manager and see if there are any strange programs or processes running.

ProcExp (free) from sysinternals.com can show you what files are opened by what processes / programs. Sysinternals has many good tools for admins.

You could also use NTFILMON (also sysinternals) to monitor just file access. You can filter by wildcards what it will monitor.

I had some good news. The files stop creating themselves and that allowed me to delete them, so I was able to make some room on the C: drive. I did notice though, that these .ctm files started and stopped themselves in June, but because the hard drive didn't max out so I never knew it. But it is still a mystery why they started and stopped.
