Understanding Maplestory and how amazing it actually is from a average gamers view.

One reason I think (thinking aloud really) that Maplestory is broken up into specific .WZ files is to alleviate the trouble of finding issues, but some .WZ files are still pretty large.

Data.wz was always split up into different sub-files. There was always Skill.wz, Character.wz, and Etc.wz, but they were all contained within the Data.wz file as subdirectories. I'll stop explaining this since now it's kinda getting off-topic.
