Update to the latest version of Photoshop CC.
Im on the latest version
You cannot bypass using a scratch disk. It is Photoshop's way of managing the temporary storage needed whilst it work on open documents. If id did not have access to temporary disk space it would be flagging out of memory errors regularly.
The fact is that 7GB of space left on your scratch disk is not much and the need to use it will be even higher with less RAM. To use Photoshop you will need to clear some space on your disk.
Just in way of comparison I have 64GB RAM installed here. I currently have 3 multilayered documents open and just checked my scratch file. Photoshop is using over 16GB of scratch space on the designated disk. It will use even more if I start merging panoramas.
Hi Dave, what im not understanding is how this was no issue on CC2017 i could use photoshop with little to no memory at all with no problems less than 1gb at some points but with this update (cc2018) it stops me?
I'm really struggling with the latest Photoshop CC for the same reason. In previous versions of Photoshop CC, 5 GB of free disk space was more than enough to perform simple edit tasks (I'm not doing large format editing, nor am I trying to do anything complex). Even immediately after doing a Purge All and restarting Photoshop, it will still complain and refuse to undertake simple operations.
I don't find this acceptable. There is no reason Photoshop suddenly requires 5+ GB free. It doesn't even try to use the space, this error is a bug, pure and simple.
For reference I'm on Mac OS X 10.12.6 on a MacBook Pro (Retina, 15-inch, Mid 2014) running Photoshop CC 19.1.15.
I too believe it is a bug.
