Descriptive metadata like 

  • ratings
  • tags
  • title, description, scene, shot etc.
  • markers
  • subclips
Is stored in xml files in hidden directories located in the same directory as the file they refer to. If you move single files around outside of Kyno the association between the file and its metadata will be lost unless you move the respective hidden file as well. Note that this is changed compared to the beta version of Kyno.


Cache data like extracted technical metadata and thumbnails is stored in the directory <user home>/Library/Caches/Kyno.
Deleting this will only affect the performance of Kyno, the next time you browse those files but you will not lose anything you entered. 

The search index used to make searching with Kyno fast is stored in the directory <user home>/Library/Kyno. Deleting this will only affect the performance of Kyno, the next time you browse those files but you will not lose anything you entered. Kyno will automatically rebuild this index on the fly, while you're browsing your files.
