My installation keeps most of the files in the base folder zipped in the pk3 files. I've had to edit the map.ufo to fix my campaign where a couple of missions won't happen due to graphics problems & the smoke grenade fix in the ufo folder, if I unzip them & edit them then move that unzipped ufo folder back into the base folder will it's changes take precedence over the unchanged ones in the ufo.pk3 file or should I move the pk3 file elsewhere?
