Photoshop: Scratch Disk Full even with all files closed problem

the question I have is I have a dedicated 80gig SSD Scratch disk, i have just done some work on a 70gig panorama 16bit file. I then close the file so there are no files open in Photoshop. I then open a 6gig file and I then get "Scratch disk Full", i check the scratch disk and find it full. I close the 6gig file and the scratch disk is still full! The only way around this is having to restart photoshop after working on large files as PS CS6 will not free it up. Even with no files open! Its incredibly frustrating as I cant do big batch processing as the scratch disk wont empty even when no files are open! I have another 100gig Firewire 800 as 2nd scratch disk, but PS just fills this up as well and I have the same problem; no files open and 180gig of scratch disks full and unable to do any more work until I restart PS. How is this possible?

What version of Photoshop? What OS/version?

If you are working on a 70 Gig image, then you need a lot more than 80 Gig of scratch space.

A general rule of thumb is that you need about 5 to 10 times the image size in available scratch space.

I know this, that's the reason i have up to 280gig of scratch disks. The problem is once a file is closed and photoshop has no files open the 280gig scratch disks are still full, they do't empty and I can't do more work without restarting Photoshop

Hi J
thanks for replying. I use OSX 10.10 Yosemite and with PS CS6. The problem also occured with OSX 10.9. Its just occured again while watching this, (i have attached a screen shot) As you can see I have a 1gig file open and the scratch disks are full. I had just finished a 225gig file over night which is closed. So I have 3 scratch disks totalling 270gig full while having a 1gig file open. I now again have to save the file and restart!!

Is CS6 up-to-date? http://adobe.ly/PS-Up-To-Date

I would also make sure that OS X has the 10.10.1 update applied.

Ys, all software is up to date, it 13.0.6 x64, just checked again and none available. I use PS3 as well and it has exactly the same problem! Scratch disks just fill up and wont empty

New in Photoshop CC (2015) - If you hold the Option (Mac)/Alt (Windows) key while selecting About Photoshop, or hold the Option (Mac)/Alt (Windows) key and select Edit>Purge>All – we flush (release) all RAM and scratch disc in use by Photoshop.
