How To Add Graphic Icon To Mac Folder

Something like this image

Any tutorial ?

TIA

Best guess would be

Have the folder on the bottom layer.

Put the feather above it. Fill 0% opacity 100% (or make the feather black and put it to screen)

Inner glow

and a gradient overlay with low opacity on darken most likely.

Here are the settings for creating these folder icons.

Thankz guys
