TMP vs Scratch disc?

Hi,
May I know what is the difference between the TEMPDIR that we specify in Adminstrator client to the disk pool that we specify in config file.

TMPDIR is on the conductor node only, scratchdisk is per processing node. Scratchdisk is explicitly used by stage types that exceed their memory allocation; TMPDIR is more generically used, and occasionally is used for files unrelated to memory allocation.

There is also UVTEMP, used by server job components.

Thanks Ray,
May I know, what files you are refering to, that utilizes TMPDIR? If we assign totally a differnt location for TMPDIR and scratchdisck, what process will utilize TMPDIR?
