Adobe Photoshop Scratch Disk Full

Adobe Photoshop uses Scratch Disks as a temporary memory for storing your documents and history panels. But, when the disk reaches its storage limit, you will come across “Scratch Disk Full” error messages. As a result, you may have trouble launching the app or loading PSD files.

Usually, these disks can get full over time when you keep opening large image preset files or when the disk cache on your Photoshop is full. Sometimes, stored auto-recovery files can also lead to this error. However, the most effective solution for solving the problem is by optimizing the Scratch disk space.
