Xzandiel's ERF Tool

Dragon Age: Origins & Dragon Age II Archive Extraction, Decryption, Rebuilding, and Repacking Utility

Xzandiel’s ERF Tool is a standalone Dragon Age archive utility built for modders, researchers, and creators who need a clean way to work with Dragon Age: Origins and Dragon Age II ERF/RIM-style archives.

It can extract, decrypt, rebuild, and repack supported Dragon Age archives while preserving the internal folder structures the games expect. This matters because Dragon Age archives are not always simple flat file containers. Many contain internal folders, version-specific layouts, and game-sensitive paths that must be rebuilt correctly.

This tool is designed to make that process easier, cleaner, and more reliable.

  Dragon Age II Support

  Dragon Age II support was a major focus of this tool.

  DA2 is very picky about archive structure. A rebuilt archive can open successfully and still fail in-game if the internal paths, hashes, archive version, or layout are wrong.

  Xzandiel’s ERF Tool supports DA2 ERF V3. 0 archives, alignment handling, uncompressed repacks, path preservation, verification, and DA2 override-style archive layouts.

  Confirmed DA2 override workflow paths include:

  packages/core/data/artfp.erf

  packages/core/data/models.erf

  packages/core/textures/high/highrescharacterartfp.erf

  packages/core/textures/high/highreslevelartfp.erf

  packages/core/textures/high/texturepack.erf

  The tool can also split oversized DA2 rebuilds into multiple archive parts when needed, helping avoid unsafe archive sizes.

  Dragon Age: Origins Support

  Xzandiel’s ERF Tool also supports Dragon Age: Origins archive workflows.

  DAO archives can contain internal folders too, and this tool preserves those paths during extraction and rebuilding. DAO support is intended for ERF V2. 0 / V2. 2 archives, with ERF V2. 2 recommended for most new DAO repacks unless you
