[HELP] armorgrp.dat

sowwy guys, i have small question

i was wondering something and tried to look for post but i couldn't find any so i had to make new one.. hope you guys don't mind.

my question is

            when you guys make new armor's and try to add the patch in armorgrp.dat, what program you guys use to add it?

for example let say:

            i have some armor / weapon / etc items CT2.3 armorgrp.dat and want to add to Interlude. what i must do to do it? any program am i suppose to use? or you have to do Manuel.

ok so other example lol, eaven i am little confused by just explaining -.-" so ill give other try

i downloaded Epic armor set from website and they are CT2.3. now i want to make it to Interlude my self... i edited SQL, Itemname-e.dat, and XML files to Interlude but i cant do CT2.3 armorgrp.dat.. giving me dam hard time to fix this..

can anyone tell me or show me easy way to do it?
