.HAK File

The hak 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).

How to open:

Use ERF Editor to work with *.hak files.

How to convert:

As far as we know, this .hak file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
