You can see the splitter algorithm option under `Repository`. It is set when you originally create a repository, so you likely are using `DYNAMIC-4M-BUZHASH` if you did not change it. You can change this to a smaller chunk size, but you will need to recreate the repository as far as I know. There are also performance tradeoffs with using smaller chunks (see the discussion at [Deduplication efficiency](https://kopia.discourse.group/t/deduplication-efficiency/1298)), but if most of your files are small, then you may benefit from a smaller chunk size.
