This has removed a further 3 MB. So thanks!
I am aware now that
- I have 2M reviews. Thats a lot of revlog on my 100k cards. That would make a ton of my collection memory
I either have to
1- Reduce my revlog up to a certain point which would damage the accuracy of my FSRS
2- Split up my decks (I am trying really hard to find decks I can give up on and send to a different profile, but at some point there will be no more decks for me to sye bye-bye to, so this is a non-option in the long run)
3- Have a custom sync server which I have no idea of setting up and where to begin.
4 - Delete unwanted decks (which I already have). There are about 4000 suspended cards which I could delete, the problem is that they are part of notes which I cannot remove.
5 - Find a way to optimize the memory size of each of my notes. (It doesn’t seem that the way I am constructing my notes is the issue though I am willing to explore that further.)
6 - Come into terms with using Anki only on my primary device, running the risk of not being able to back up or sync across all my other devices and waiting for however long that Anki allows a memory expansion service.
In any case, I have 45 MB of free space now. Sooner or later I am going to be here again and I am going to have to do something about it.
