Morrowind Mod:Wrye Mash

A UESPWiki – Sua fonte de The Elder Scrolls desde 1995

Wrye Mash is a general purpose utility for managing and repairing mods and savegames. Currently it is the only tool that systematically prevents doubling. It combines multiple mod-management capabilities making it one of the most strongly recommended utilities for both modders and players. There are now several versions from which users may choose. All offer the same functionality for handling installer packages, mods and savegames through a GUI. A tutorial (in pdf format) is available from vermin.
