I have several .ics files because I would archive once a year to keep my desktop app speedy. I've imported the most recent into google calendar to use with the droid, but if I go and import one or more of the older ones, do they add/merge or will it delete the current. When testing goole calendar originally I imported the same ics a few times and it always seemed to replace what was there so I'm wondering if 2008's ics will replace 2009's and so forth.
