What is a .ato file?

An ATO file is a recorded sequence of commands and actions that you can play back in Adobe Photoshop. These actions automate repetitive tasks, such as applying specific filters, adjusting colors, or resizing batches of images. By recording your steps, you create a reusable script that saves significant time and ensures consistency in your image editing workflow. They are incredibly useful for professional designers and photographers who handle large volumes of images requiring uniform edits.

When executed, Photoshop interprets these instructions to perform the recorded operations sequentially on an image or a batch of images.
