How to Fix Photoshop Scratch Disk Error on Mac?

In the world of Photoshop, a scratch disk refers specially to a portion of hard disk space used for temporary storage. This allows Photoshop to perform operations requiring more memory than it is available from the system RAM. Photoshop uses this space for creating the temporary files and deleting them after they are no longer needed. Photoshop’s temp files are typically named as Temp#### on Macintosh, where #### is a series of numbers. These are safe to delete.

The Photoshop encounters scratch disk full error due to below mentioned three reasons:

  • Photoshop crashed: The Photoshop application creates large temporary files on scratch disk and deletes them when it is finished, but if the program does not shutdown properly, then these files can be left on the disk and you may encounter errors
  • Working with large image: You may get this type of scratch disk full error message when working with particularly large images, Photoshop application needs huge space than usual to accommodate the image editing
  • No space on scratch disk: If your scratch disk memory is full then “scratch disk full error” message occurs when you start the Photoshop application or while editing the image on Photoshop program. You might even notice missing of PSD files when during scratch disk error. However, there is an opt way to recover back PSD file disappeared from Mac Machine or Windows given in the link.


You can easily resolve “scratch disk full” error by deleting the temporary files that are left on the scratch disk. If it shows the same error message again, then just delete the unwanted files from scratch disk or you can assign new scratch disk by setting some preference on Photoshop application that allows you to use multiple hard drives. Even after doing all these things you are getting the same error message, then defragment your scratch disk.
