The installation makes it possible to use its three main tools specifically an archive viewer alongside editor and file manager which accelerate the modding workflow. OpenIV users can access automatic backup features together with ASI Loader integration and the OpenIV.ASI plugin which enables safe mod execution without changing game files permanently.
