Selecting Scratch Disks
Performance preferences are available to help you get the best performance out of your computer by letting you choose one or more hard drives for scratch operations. When your computer doesn’t have enough RAM to perform an operation, Photoshop uses free space on any available drive, known as a Scratch Disk. Photoshop runs faster when you divide the Scratch Disk workload. Scratch operations are performed on your hard drive and take place when Photoshop is using one of its many filters and adjustments. Photoshop detects and displays all available disks in the Performance preferences dialog box, where you can select the disks you want to use. By assigning additional hard drives to the task, you speed up Photoshop’s overall performance. Scratch Disk changes take effect the next time you start Photoshop.
Work with Scratch Disks Options
- Click the Edit (Win) or Photoshop (Mac) menu, point to Preferences, and then click Performance.
- Select the check box next to the scratch disk you want to use or clear the check box to remove it.
- Click OK.
