Photoshop CC 2018: Seems to "eat up" spare HD space again

I have just updated to the latest Photoshop 2018 and have been working on photos all day. I noticed that my free HD space has "shrunk" by about 40GB in a matter of a couple of hours. I know I've seen that happen before, and it was fixed in one of the previous releases (I posted about it, then I actually thought it was Lightroom's fault).

I've used them both today, but I've now quit LR but still see the space being gone. My HD is almost maxed out, it got to just a few GB's of spare space. 

Please investigate ASAP

Immediately before and after I quit photoshop.  When I quit, I got a message saying that the clipboard is really large and can't be exported. Why is 40gig of data saved in clipboard??

What sort of operations are you performing? Painting, batch processing, actions?

Hi Svetlana,

While I doubt Photoshop is holding 40GB of data in clipboard, it does continue to use RAM until the app is quit and relaunched (when it needs more, otherwise it'll re-use the RAM it already has allocated).  All RAM that's used by PS is also mapped to your hard drive which would explain some of the disc usage you're seeing.

It would really help if you could describe your workflow.  What exactly are you doing with images?  Are you copying data/selections and pasting them into other images?  Any information would be helpful so that we can try to replicate what you're seeing here.

Thanks,
Adam

Hi Jeff, Adam,

Thanks for the quick reply. In this current session, I wasn't doing much of copy/paste, except for one small section of one of about 20 images I edited. I was simply re-saving a bunch of my TIFF files with a compression (I had them all uncompressed). I have photoshop running now again, with about 7 images open, doing the same thing, and my HD space went down by 20GB now. I realize that the RAM used maps to HD space, but I don't think my usage should equate to 40GB of hard drive space. Here are some memory and HD stats as of right now



Let me know if I can share anything else that's helpful.

Thanks,
Svetlana

And after I quit Photoshop it's up to 77GB from 41GB. No trash has been emptied, no other apps (besides the browser and the file manager) actively used

Svetlana, what size/file type/bit depth/# of layers are the files you're opening?  I'm not seeing that much disc space being used opening files, but I must be using smaller images.  Thanks.

Also, if you could set the image window info to scratch sizes (see below), and tell me what those say when your disc is filling up, that would be really helpful. Thanks again.

@Adam, I have just launched photoshop to merge 11 raw photos to a panorama. Before opening photoshop, via Lightroom > Merge to panorama in Photoshop, my spare HD space was 89GB. 
Now, after the merge is complete, it's 59GB (and going down, 57GB a minute ago and 52GB now, by the time I finished writing this). And the only open file is the merged panorama with the scratch size of 9GB that I haven't touched yet, after the merge completed.
The files are CR2's from my Canon 5DMK IV, so they are quite large. But only about 40MB each, unedited.

Uhhh, if you're merging 11 30Mpx raw files, you'll be using a ton of scratch. What you're seeing is working as expected. And given that your HD is already nearly full, PS is going to be having a really hard time writing that amount of data to the scratch. I'd suggest clearing at least another 20-30GB off your HD.

How much RAM do you have installed?

@eartho, I realize that it needs a lot of memory, but I think there is room for improvement - using 40GB for 3GB worth of data doesn't sound right. I have 16GB of RAM installed and there is a screenshot above showing what is average performance by Photoshop  - using about 6 out of 16 available.

"using 40GB for 3GB worth of data doesn't sound right."

while it might not sound right, what you're trying to accomplish with an 11 image 16bit! stitch always will and always has used that much scratch. This is simply the byproduct of hi-res image work.

As a retoucher who does a lot of work on massive files, i have 100's of GB's dedicated to my scratch and i often see it with over 80GBs filled.

Like i mentioned before, if you want to work on 16bit files with that many layers, you need to have a large dedicated scratch partition. There's absolutely no way around it aside from creating smaller images.

After finishing and quitting, I'm up to 94GB. The file was flattened and saved as a 1GB TIFF somewhere in the middle of the process, but the HD space didn't change until after I quit Photoshop.

@Jeffrey, thanks for the tip! I will give it a try and will report back. I think it would be great to include it in Photoshop help! I'm sure I'll forget it 6 months from now and will scramble, trying to remember where I saw this tip.
