In my calendar-data\backup folder I have over 40 .ics files (spread over five calendars) They vary from calBackupData_1481772182158_edit.ics to others ending with thing like: ….day.ics, ….day-2.ics,….day-3.ics,…,...edit.ics, ...intial.ics. Now when I started on trying to backup and tidy the calendar files, there were perhaps five or ten of these files. Is there a reason why they’ve multiplied? Are they breeding? Earlier I needed to restore some backups, which had been exported as .ics. When I clicked on the calendar and pressed delete, I was asked “Do you want to unsubscribe from the calendar “personal”?, followed by “unsubscribe” or “cancel” I assumed (dangerous I know) that the unsubscribe option deleted it from the system? Then I imported the backup I wanted. It’s making me wonder now if it was deleted or just ignored? Since having imported the backup, I notice when the calendar reminder pops-up, it “pings” twice now, whereas before it was only once. Something else I’ve noticed is that when I pick an event entry to edit, if I click Category, a dropdownlist appears. I remember adding an entry to that list called “Payments”. However, only some of the events have that customised Payments item in the list. Is there perhaps something I should do to make sure when “unsubscribing” that the calendar is deleted, before importing another one? Have they merged, or duplicated?
