If after seeing that message you closed Photoshop and then restarted Photoshop which I think you may have done for Windows does not run well when your C: disk becomes full. If You terminated Photoshop because you got the message and Windows was not running well. The scratch space the Photoshop had allocated would have been returned to C: disk free space. Also 856MB is not much free space I have seen Photoshop use much more free space than that on my system. Many GB in facts. Photoshop also create temp work files in your user id temp space which is also one you C: disk. I feel you need to free up space if C: is the only disk you have.
I just closed PS
Free space is up to 129GB
you should consider a 1t external drive to use as a time machine/backup and add it to that dialog you have open for Photoshop to go in there first before going to your C: drive for scratch disk space.
Hi, how did you open the right 'Photoshop Temp' window? I cannot come to it..
Basically I also have the same problem, I have a new laptop, 'the machine' and all, I thought 500 gb Ssd disk is gonna be a blast. Next thing I know, 6 months latter I am getting reports that the C disk is full??? Besides Windows, Microsoft, Adobe and Mendeley I have nothing on the laptop, I am even using Microsoft Explorer - its really solely photo and video editing laptop.
I have never had this problem before, so I have came to the conclusion that it must be scratch disks and catche data.
I turned internet upside down and I cant find an article saying where can I empty scratch disk. Would somebody please be so nice to share this knowledge with me?
Jonathan, some external hard drives are not accepted as Scratch disks, if they are recognized by the system as removable, but setting up a time machine backup is a big plus, indeed!
Hello Zala, what might happen is that if Photoshop crashes, it might not delete the scratch file, and it clogs the C: drive.
Some users also had the problem when trying to crop an image using the wrong units, 1920x1080 Inches is way different than pixels at 300ppi...
Thank you for your answer. So what I was thinking of doing is uninstalling Photoshop, deleting all the files off the SSD and installing them again. That is logical thing to do, right?
Can you explain what you mean with the cropping units? I am using crop tool, 300ppi is just a 'quality' of photograph, right?
The cropping units are available if you select WxHXResolution instead of ratio in the option bar. (in the latest versions, do not remember how cc was)
Anyways, make sure that you enter 1080px instead of 1080in if it is what you want...
I'd try first to reset the crop tool in the option bar, right-click on the crop tool icon.
I'd then try to delete the preferences, look in Edit>Preferences.
