What is a .COS file extension?

.COS is Capture One Settings File

Image settings file created by Capture One, a program used for editing and organizing digital photos; saves image adjustments (exposure, color temperature, white balance, etc.) and other nondestructive edits for a photo.

When image adjustments are made, Capture One saves a COS file that has the same name as the original image but with the added ".cos" extension. For example, if you make adjustments to myphoto.jpg, Capture One saves a myphoto.jpg.cos file. When final adjustments are made, you can process, or "bake," the settings and photo together into an output image with all adjustments applied.
