The setting was not set, so I expect that it used the default value of 3.
I tried setting it to 1, and restarted the server, but nothing happened
with the directories. Is there something that triggers the cleaning of it?
Another thing, I dont understand how a setting of 3 leads to 7 files since
one segment is 16MB, 3 segments should be be 3 files i.e. 48MB not 113MB.
Am I misunderstanding something?

Can you be a bit more specific? I tried looking for it, but the sections
are too big to just browse unknown information.
