I have around 100 .csh files I'd like to import into Photoshop on my Windows 10 PC. I can import one .csh file at a time, but I can't seem to figure out how to import more than one at a time. I can't use Shift or CTRL to select more than one.
I did find a video on YouTube where someone could do this, but they were using the Mac version.
You can import multiple .csh files at once on Windows by dragging and dropping them:
Open your File Explorer and navigate to your .csh files
Select the ones you want to add
Drag and drop them either on top of the Custom Shape dropdown in the options bar (the Custom Shape tool will need to be selected for it to be visible there) or on top of the Shape panel (Window > Shapes)
