SparkIV is an IMG and RPF archive file editor for GTA IV, created by aru. As of version 0.5.1 the software is open source, released under the GPL v3 license.

It includes viewers for several file formats commonly found inside the archives, such as textures (*.wtd), models (*.wdr) and model dictionaries (*.wdd), as well as a decompiler for the game's mission script (*.sco) files.
