How to force database file size maximum limit?

Hello,

I found filesize.max.other in advanced configuration.
According to defaults/yacy.ini, that value is set to limit the database file sizes
It was set to 8589934591. I guess it’s in bytes. I’ve changed it to 1589934591.
I still don’t see a difference. There’s still file of up to 9GB
The defaults/yacy.init is still at 8589934591

So how, where and when is this variable is taken into account? Where do we limit the size of the database files?

thank you.
