Well for instance Animations.cs you would do this

        private static FileIndex m_FileIndex = new FileIndex( "Anim.idx", "Anim.mul", 0x40000, 6 );
        public static FileIndex FileIndex{ get{ return m_FileIndex; } }

        private static FileIndex m_FileIndex2 = new FileIndex( "Anim2.idx", "Anim2.mul", 0x10000, -1 );
        public static FileIndex FileIndex2{ get{ return m_FileIndex; } }

        private static FileIndex m_FileIndex3 = new FileIndex( "Anim3.idx", "Anim3.mul", 0x20000, -1 );
        public static FileIndex FileIndex3{ get{ return m_FileIndex; } }

        static Animations()
        {
            Initialize();
        }

        public static void Initialize()
        {
            Utility.EnsureClose(m_FileIndex);
            Utility.EnsureClose(m_FileIndex2);
            Utility.EnsureClose(m_FileIndex3);

            m_FileIndex = new FileIndex("Anim.idx", "Anim.mul", 0x40000, 6);
            m_FileIndex2 = new FileIndex("Anim2.idx", "Anim2.mul", 0x10000, -1);
            m_FileIndex3 = new FileIndex("Anim3.idx", "Anim3.mul", 0x20000, -1);
        }

Then make a Utility function EnsureClose

        public static void EnsureClose(FileIndex fileIndex)
        {
            if (fileIndex != null && fileIndex.Stream != null)
            {
                fileIndex.Stream.Close();
            }
        }

Be sure you inlude your custom paths, and whenenver the custom path changes call Animations.Initilize();, just do this for each class that has a FileIndex in it.
