What is a COSESSIONDB file?

A COSESSIONDB file is a session file created by Capture One, a program used for managing digital photos. It stores a collection of photos that have been selected by the user and organized as an album. COSESSIONDB files are used to organize your work as a project.

More Information

COSESSIONDB files are located in "Sessions" folders in the Capture One directory on your computer. COSESSIONDB files replaced .COL, COL 60, COL50, and COL45 files, which were used by older versions of Capture One. These older files can still be opened by Capture One.
