Curt Y Aug 12, 2010 11:42 AM (in response to Shan-Dysigns)What you are seeing is normal. History states is a big driver on
how much scratch space is needed. If you have a 100 meg file and modify the whole layer, like with a gausian blur your image file is now 200 meg. Each operation adds to it.

Shan-Dysigns Aug 13, 2010 1:53 PM (in response to Curt Y)I've got my preferences to allow 10 states in History to be kept (down from the default 20 - I think).
Here is another recent example:
I open Photoshop - a scratch file of 2+ GB is created. When I'm done with that particular file and close it, the scratch file is now 7+ GB. Why wouldn't that scratch file drop back down (kind of like how available RAM is used)?

I'm more curious than worried. I had never really paid any attention to the scratch file until I happened to open the drive I've assigned the scratch file and noticed such a large file. Like I said, this particular project I'm working on is quite large, and Photoshop seemed to be struggling more than usual - that's what lead me to look around to see what might be causing this - that's when the scratch file was 100+ GB and there were 3 of them. If such a large scratch file is common, I will let it be...

Save your work and close PS, then see if there are any left. You can safely delete them when PS is not running.
