I've long had my calendar files stored separately to the calendar application, to make it easier to find when connecting it to different Sunbird/calendar variants. However with Sunbird Portable, it seems to insist that they live at:
All of my attempts to move them to a path outside of SunbirdPortable\ results in SunbirdPortable changing their locations back to the default (and ending in empty calendars).
Is this intended? Other versions of sunbird etc. let the calendar files be anywhere.
