Those darn scratch discs

Hi Everyone,
Can anyone tell me how to deal with the darn scratch discs? I have spent hours trying to figure out how to get Photoshop to stop telling me they are full but have had no success. I have three drives listed where the stuff it puts on scratch discs can go and it says they are all full. One of the drives has quite a bit of free space but that doesn't seem to matter. I have tried purging the program and that didn't help. I looked it up on Google and it says you can empty the temporary files but I'm not sure where to find them so I can do that and I don't want to get rid of something I need. Is there a way to get rid of those files? If so can anyone give me the exact way to do it? I have also looked at youtube for help and didn't find much there that was useful. So any and all help would be really appreciated if you have a minute. Thanks in advance and I hope you're having a good week.

Hi @maggie2
Have you checked out this troubleshooting video from Adobe?
https://helpx.adobe.com/photoshop/kb/troubleshoot-scratch-disk-is-full.html

Can you be more specific, Marg, about the free space available on each drive you designated as scratch disks and whether they are regularly hard drives (HD) or Solid-State Drives (SSD)?
It is surprising how much temporary space is needed while Photoshop is running. How much you need depends on many factors, such as the number of open PS documents, the size of each document, etc. In the video, they mention having 50 GB as a starting point, yet recommendations typically are very low-ball numbers.
Also, freeing up scratch disks across many hard drives is not always as effective as having a lot of scratch disk space on one drive.
The advice you got about freeing up temporary files is one of the generic ways of freeing up disk space. An example of temporary files is when you delete files, they go into a trash bin. When you empty the trash bin, you free up those temporary files.

A rule of thumb I follow for many reasons is that my Hard drives or SSDs should never be more than 50% full. When they get too full, disk performance goes down, and obviously, you push up against the limit of room for scratch disk space, too. Some may say that sounds like a waste yet I am at least not wasting as much time on HD / SSD problems.

Just some quick thoughts.
I hope this provides some thoughts for consideration.
