What is COL file?


A COL file extension is a file that contains information about the settings of a photo. It contains all the settings that were applied to the photo and can be opened as a separate application. For example, if we open a raw image in Capture One, it will automatically create a COL file. The COL file contains data such as shutter speed, aperture, focal distance, etc.

Sometimes you need to quickly preview the contents of a file with the COL extension. In such a situation, many people decide to find a tool that, according to its creators, can display the contents of the COL file and many other types of files (All in One Viewer).
