Yea as has been stated, the game reads any ini file that is in the object folder...so the amount really doesn't matter. v026 had 111 ini files in there (1 ini for almost every unit).
I believe that the game also reads any ini's that are inside any folders in the object folder...
example: if i wanted to I could split up the inis so its like this
gen/data/ini/object/allied units/<allied ini's> and so on
it really helps with organization and such
