What is a CK9 file?
Backup file created by Cook'n, a program used to store cookbook recipes; contains a backup of a .DVO cookbook file; used for recovering lost data in the event that a DVO file is lost or corrupted.
To create a CK9 backup file, select File → Backup and specify a backup location. To restore a backup file, select File → Restore.
NOTE: Use caution when restoring a backup file since all current cookbook data will be overwritten.
