Creating Droplets
By creating a droplet, you can tell Photoshop to perform the same Action for every file in a folder by simply dragging a folder (or a set of images) onto the droplet. First create an action, then go to the File menu and select Automate > Create droplet. In the Droplets options window, select what action to play, and where to save the droplet.
Once you’ve created the droplet, find the droplet in your computer and start dragging and dropping files on to the droplet!
