Scratch Disk Full MAC: How to Clear Storage & Remove Duplicate Files

A scratch disk is a part of a Macbook’s hard drive space that Photoshop uses as a virtual memory source whenever the RAM space isn’t sufficient to complete a certain task. If you are a media professional or even a student who works on Photoshop, you might have encountered the “Scratch Disk Full” error at one point or another. This is usually caused by the numerous temporary files Photoshop generates on your Macbook.

Luckily, there are a few things you can try to overcome this problem and enhance your Macbook’s performance. 

Clear Storage (Cache)

One of the simplest ways to fix this problem is to clear your Photoshop cache. 

  • Once you have opened a file in Photoshop, go to Edit from the main toolbar. 
  • Go to Purge.
  • You’ll see options like Clipboard, Histories and All. Select All to delete all of your caches.

Hopefully, this will fix the problem immediately (at least for some time until cache accumulates again).

Alternatively, you can try to delete the duplicate temporary files present in your device. One of the most common reasons for a Macbook becoming slow is low storage and one of the main reasons of low storage is a high number of duplicate files. The solution to this is simple: Clone Files Checker. 

Delete Duplicate Files with Clone Files Checker

Clone Files Checker is currently compatible with MacOS 10.14, 10.13, 10.12,OS X, 10.11, and 10.10. Not just images, but it can also successfully detect duplicates for all other file types including videos, audios, documents, and archives. 

Using CFC is a walk in the park. With 3 simple steps, you can discover and remove thousands of duplicate files lying around your Macbook. All you have to do is:

  • Scan your Macbook (will only take a few seconds)
  • View the report (classified by file types)
  • Delete or Relocate Duplicates

and that’s it! Within seconds, CFC will help you to recover several precious gigabytes. Before you begin your scan, you can specify the file types or file size ranges that you want to include in your scan. You can either run a full-fledged scan or a customized one. 

Additionally, while deleting duplicates, you can decide on the basis of several different factors such as:

  • Newest
  • Oldest
  • Most modified
  • Least modified
  • File location etc. 

Apart from helping you fix the “scratch disk full” issue, running a Clone Files Checker scan will also help you recover lost storage space, organize your data in a better manner, and most importantly enhance your device’s speed and productivity. 

Hope our suggestions helped you fix the issue and work on Photoshop smoothly again.
