how to change address of my TEMP folder

Ok, so when I recently reformatted my hard drive i decided to put windows xp on a small partition to keep things clean. What I didn't realize is that now if I'm editing large photoshop files for example, I'm running out of memory, because of the huge temporary image files being stored on my c:/ . Is there a way in windows XP to change the location of your Temp folder, so i can have it store stuff on my other much larger partitions?

Or am I pretty much screwed?:(

For photoshop, go to the properties dialog and change the "Scratch disk"

Cool thanks.

A friend showed me later that you can actually edit your temp folder address. Under control panel>system>advanced>environment variables

From there you can just edit the address of the folders....in case anyone was interested.
