Metin2 EPack32 and EterManager are classic client pack tools used to extract, edit, and manage Metin2 EPK/EIX files. These tools allow developers to access game client resources such as UI elements, textures, models, quests, and system data. They are commonly used in Metin2 private server development for client customization, debugging, and resource editing. EPack32 focuses on unpack/repack operations, while EterManager provides deeper file structure management.
