What is an .COL file?

.COL is Capture One Session File

A COL file is a session file created by Capture One, a program used for managing digital photos. It stores an organized collection of photos selected by the user and supports folders and virtual albums. COL files are often used for organizing pictures from trips or photo shoots together.

COL files have been replaced by .COSESSIONDB files. They can still be opened by Capture One along with COL60, COL50, and COL45 files.
