Is it any way or tool to clear db4o files ? Ie. delete old data ?

I don’t know personally, but it looks like @rlkoshak just answered this question!

db4o reduce size of "store.db4o"?

55 mb is really not that big. I’ve seen db4o files in the multi-gigabytes that perform just fine. And the way that DBs work the size of the DB rarely impacts performance until they get so big they no longer fit into RAM, and even then not much. I do not know if there is a way to clean the DB, though it seems like some sort of mechanism would be useful for the embedded databases like db4o. Because db4o is an embedded DB it does not appear to have a lot of tools you can use outside of writing you…
