Can some one tell me how to read images from a folder and save those edit images in a different folder?

I know there are options like "import as stack" or "export > layers as files" but I am dealing with a TON of images and I want to let it do this while I am away from the keyboard. Basically I have written the main process of editing the images the way I want it to be edit. So far I am using import as stack and I want to change that so I don't have to do it. The same thing goes for saving, I don't want to click on "export > layers as files", I want something fully automatic. Can someone please point me in the right direction.
