Scratch Disk
Hi, the Photo Editor on my Elements 2021 won't open. Error message states that the scratch disk is full. I set the scratch disk to be an exterbal hard drive which has masses of free space so that can't be right. I'm on Windows 10. Online solutions all say open Edit/Preferences/Performance to check settings but when I open Edit/Preferences in Organiser there is no tab for Performance. Please help!
