About BIG files

BIG files are proprietary data archive files commonly used in video games to store game data like textures, sounds, and models. They are not easily accessible without specialized software, making conversion challenging. Key extensions include .big, and they can be converted to formats like .zip, .rar, or other archive formats to access the contents.

Conversion Software

For Windows users, Dragon UnPACKer is a useful tool that allows you to open BIG files and extract the contents. Another option is Total Commander with the appropriate plugins. For Mac users, tools like The Unarchiver can sometimes handle these files, although support is limited.

Considerations and Challenges

When converting BIG files, it's important to consider the potential loss of data or format fidelity. Some files within a BIG archive may not convert cleanly due to proprietary or complex encoding. Additionally, converting these files often requires technical knowledge and can be time-consuming.

The BIG Converter Story

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our BIG converter.
