Hello,

We have been using Thunderbird for a couple dozen years here, with constant publishing/subscribing family & friends-wide. All of this may look simple and naive, but we are reaching a stage where the super-old agenda exports near 1Mb, which is definitely problematic both for transfers (it seems ftp now fails?) and even, now, parsing.

Of course everyone wants to maintain its own archive, nobody wants to change urls, etc.
At this moment I'm considering asking them to 'stop here' and restart some 'myagenda2' which would become the only published one.

Instead of launching all this irreversible stuff, I would have preferred 'just saving all old events to a kind of archive' similar to what we do for mail files, but I don't really see a way to do this on Thunderbird.

Would you have some advice on this?

TIA!
Herve

I found this:

"Thunderbird stores the calendar data of local calendars in your profile folder in the file calendar-data/local.sqlite, an SQLite database file."

So that's something you can open easily with DB Browser for SQLite although editing it may be tricky.

I suggest you zip that file, move the zip elsewhere then open the agenda and delete all the old stuff or some of it. I mean, do you really need to preserve 24-year-old events and appointments?

If this is really important to you, you may investigate ways of keeping two databases, a big one and one with only the most recent events, and how to incrementally add the small recent DB to the large historical one every so often without damaging it. If you do that, then you'll have to learn a little bit of SQLite DB administration.
