Game file type icon Game file type

The erf file extension is mainly related to Bioware Aurora game engine and used for its default archive format.

The Encapsulated Resource File (ERF) format is one of BioWare's methods of packing multiple files into a single file so that they may be treated as a single unit. In this regard, it is similar to .zip, .tar, or .rar. BioWare Aurora Toolset files that use the ERF format include the following: .erf, .hak, .mod, and .nwm. The example ERF Editor is an internal BioWare tool (Windows only).
