Batch script for photoshop focus stacking

Hi,

Im trying to write a script/action to batch edit a jewelry focus stacking job on a Mac.

I would like to make a parent folder with subfolders, have the action open each subfolder, open contents of subfolder as layers in PS, auto align, and blend layers (run the PS focus stack script). Then merge layers, save in a "finals" folder, and then auto move on to the next subfolder and repeat.

Would appreciate any help!

Thank you
