No where to add new scratch disk in Photoshop (2023)

[Damn Handsome]

Hey there, 

Where is the button to click to add a scratch disc?

[Bojan Živković]

Photoshop should automatically detect available disks, and then you will have the option to select which disk to use as the scratch disk. I am not aware of a button to “add” a disk, as this should be done automatically. Make sure that your disk is properly connected.

What kind of hardware are you talking about? 

[D Fosse]

The scratch disk is not a Photoshop setting. It is actual, physical disk space. You need to purchase a new/bigger drive, or clear out space in your old.

[Chuck Uebele]

As others have mentioned, you need another physical drive attached to your computer. Do you have one attached?

And the kind of drive may also make a difference (see »Supported drive formats for scratch disks«):
