Lets cut to the chase Photoshop seems to depend on scratch disks in order to be of use, The file that houses these temporary files shouldn't be so hard to find in fact it should automatically be clearing itself after the user gives photo shop permission to do. I am posting here because this should be an update that is on the books no time should be wasted for something photo shop should be doing automatically.

It's not clear that you understand scratch disks. It's free space on your computer that Photoshop needs while you are working on a file. How much free space do you have on the drive you have allocated for scratch space/disk? How big are the files you are working on?

Here are two help files from Adobe that explain:

No, Photoshop needs no scratch disk IF (big if) you have enough memory to store 3-5X the file size in actual RAM. If that isn't the case, then it uses empty disk space as if it were RAM (much slower but still doable).

Once you are done with that image or open images, that space becomes empty. And there are several ways to see if, indeed, PS needs a scratch disk, such as this area of the open document window called Efficiency; falls below 100%, PS needs scratch disk. There is nothing to find on a scratch disk!

Photoshop will use scratch disk regardless of RAM size. I have 256GB RAM here (the PC was built for 3D physics simulations) and scratch disk is used even with no files open or very small files. I have no issue with that - just clarifying for anyone who thinks loading up with RAM will alleviate the need for scratch disk space, it won't.

Good point, Dave. I was trying to remember how how scratch disk space you and DFosse recommend?

The first help file I linked to has a paragraph that starts with, "Minimum free space on a scratch disk should be 6 GB for Photoshop desktop." It's not until the end of the third paragraph that it says, "you could need as many times the size of the original file".
