How to Solve Photoshop Scratch Disk Full on MAC and PC

Photoshop scratch disk full is a pervasive problem where your hard drive runs out of storage space to perform tasks. You may have noticed that your computer slows down dramatically when working with large files in Photoshop. 

This is because of the lack of available space on your computer’s hard drive, which results in a slow processing speed and sluggish performance. You can fix such an issue by:

  • Changing your hard disks 
  • Clearing your Photoshop cache 
  • Clearing disk space and more

Here is more insight on what you can do to fix it!

Create a New Drive for Your Scratch Hard Disks 

Creating a new drive for your scratch hard disk can help solve your Photoshop issues. Increasing scratch hard disks is a good idea if you want to keep your computer running smoothly and prevent Photoshop from crashing. You can increase your scratch disk in Photoshop by going to the Edit menu and choosing Preferences

Next, select Scratch Disks from the list on the left, then click on a new drive in the Destination Space area at the right. Finally, click Save after making changes. You’ll have to restart Photoshop for these changes to take effect, so, select ‘Restart’ when asked. This is an easy way to solve Photoshop scratch disk full on a Mac or a pc.

Create More Space on Your Photoshop Cache 

Photoshop scratch disk full errors are typically caused by the lack of available physical memory (RAM). Photoshop works with large files or complex documents requiring many resources, such as images above 30 megapixels and high-resolution videos. 

This problem can be easily solved by clearing your Photoshop cache. First, quit Photoshop, locate your “cache” folder, delete it, or drag it to the trash can. Then relaunch Photoshop for the changes to take effect.

Delete All Temporary Files

Deleting temporary files is another easy solution to solving your Photoshop scratch disk full issue. The first thing you want to do is select the ‘Empty Trash’ option from your computer. One can do this by going into Finder, choosing “Macintosh HD,” and then double-clicking on the ‘Trash’ file. 

Then follow through with deleting all of your temporary files that are taking up space! You may need to empty trash multiple times depending on how much free space there currently is in your hard drive. 

However, you should only delete these files once if this is an ongoing problem for your Mac or PC machine. If this doesn’t solve your Photoshop scratch disk full issue, then you should try a more advanced solution.

Delete Items on Your Disk to Create Space 

You can try clearing disk space to solve your scratch disk full on mac and pc.  The first thing you should do is free up some space from your HDD or SSD by getting rid of old, unwanted files such as videos, photos, apps, and other junk files, which will take a lot of storage space. 

You can also try changing the location where Photoshop stores its temporary data like scratch disks which usually take too much room in your system drive. Be sure to go to Edit > Preferences > Scratch Disks, and then select a custom location from the list.

Rearrange Files in Your Hard Disk

To solve the scratch disk full error, you need to defragment your hard disk. This means rearranging all of your files to be stored in one contiguous section on your drive. If a file is fragmented, it will be split up into many small pieces and can slow down performance. 

Numerous third-party tools for both Macs and PCs make this task relatively easy (even though there is no way around it being time-consuming). You can use Windows Disk Defragmenter to defrag a computer’s hard disks. 

First, launch the tool from Start Menu > All Apps > right-click on “System Tools” and select Open, or search for it in the Cortana search bar by typing “Disk.” Note that defragmentation is unnecessary if you have an SSD disk (Solid State Drive), but you should still keep the drive well-maintained. You can do this using the Windows Optimize Drives tool, which should come preinstalled on your system.

Boost the RAM Allowed by Photoshop

To solve the scratch disk full-on Photoshop, the first thing you need to do is check your RAM. How much RAM do you have on your PC or MAC? If it’s more than 12GB, then that is a great start. However, if not, there are steps to increase the amount of RAM allowed by Photoshop.

First, close all other memory-intensive applications. If you have many open, close them before launching Photoshop. Quit any other programs running in the background on your computer (for example, iTunes or Skype) and finally delete unnecessary files and clear up some space on your hard drive – this frees up memory for use by Photoshop.

The above are some of the most practical ways to solve Photoshop scratch disk full on MAC and PC. Consider them if you ever experience such an issue.
