Hi,

Someone else asked my question a year or so ago and there were no replies but I thought I would give it another go.

I would like to know if there is a way to redirect the ArcHydro Temp directory to another drive. I am using ArcHydro 2.1.0.116 with ArcGIS 10 on XP.  The currrent default directory for archydro's temp data is on the c: drive.  Due to either HP's or our IT Departments infinite wisdom the c: drive sits on a small partition so  I need to redirect the temp directory to another drive.  I am using large datasets so anytime archydro has more than 2 intermediate grids in its calculations it uses all the space and falls over.  I have removed programs and cleaned up the c: as much as I can, I delete the temp directory by using the feature in archydro but it still does not give me enough space.  I have tried to redirect ArcMap's general temp directory to my d: drive but this has no effect on ArcHydro files they still go to the c:.

Any help would be appreciated.
Regards
Tim

Arc Hydro is using your default windows temp environment.
In XP, you can change it by right-clicking MyComputer (on your desktop or in windows explorer) and select Properties.
Then click the Advanced tab and click Environment Variables.
Modify the path for the TEMP user variable.
