My “c:\” Drive gets full when I open the profiler trace
Posted by Karthick P.K on July 16, 2011
Profiler filling up space of my system drive…….
When you run the profiler trace (GUI) or open the saved profiler trace file your System Drive gets out of space
SQL Server profile uses ‘TMP’ Environment variable for storing the .Trc and trace replay files
By default TMP directory points to your system drive, so when we open a large profiler trace file or capture trace in GUI mode system drive gets full.
We can workaround this by changing the TMP environment variable. Changing TMP environment variable system wide can cause other issues so I would recommend changing TMP temporarily for the process
1. Open command prompt
SET TMP=G:\TMP
2. Open the profiler from command prompt
>Profiler90.exe –>SQL Server2005
>Profiler.exe –>SQL Server2008
>Mysavedtracefile.trc –>Open a saved tracefile
This would make profiler use G:\TMP for saving temporary data. So your c:\ would never get full.

Nice article. This was exactly what I need. However, my temp files are still writing to my C drive. Any other ideas. I have tried

and your article and it’s still increasing the size of my c drive..

I finally used process monitor from SysInternals to see what directory it was writing to. It was actually writing to my local user directory. So, I followed the directions in the below link, but changed the User variables instead of the System variables and my temp files started getting copied to the appropriate directory after that.

What exactly you did when you mentioned that you changed the user variables instead of system variables?
