Where can I find the data files associated with KOrganizer. I need to symlink them into non-volatile location. Just installed on Ubuntu 18.04

Check the KOrganizer settings and the configured calendar sources. For each calendar hosted local or in a file (ical file or folder) you will find a path there. For other calendar hosted as remote resources (Google calendar, Kolab, MS Exchange, ...), there is no such think as data file. They may store the appointments in many files, database or IMAP folders.

Thanks for the quick response. Exactly what I was looking for.
