.BMS (QuickBMS Script) - File Extension

What is a BMS file?

A BMS file, with the “.bms” extension, is a text-based script used by QuickBMS, a tool that extracts assets from video game archives. It contains instructions written in the Binary MultiEx Script (BMS) language, guiding QuickBMS on how to extract specific data from various file formats.

BMS files are like roadmaps that help unlock and extract valuable content from video games, making them accessible for customization, modding, and analysis. Unlike binary files, BMS files are human-readable, allowing users to create custom extraction scripts without the need for complex programming knowledge.

How to Open a BMS file

Opening a BMS file requires the use of a compatible software program such as QuickBMS itself, which is freely available for download. To open a BMS file, follow these steps:

1. Download and install QuickBMS from the official website.
2. Launch QuickBMS.
3. Click on the “Script” option in the menu bar.
4. Select “Load” and navigate to the directory where the BMS file is located.
5. Choose the desired BMS file and click “Open.”
6. QuickBMS will load the script and display it in the main interface.

Once the BMS file is opened in QuickBMS, users can execute the script to extract assets from specific file archives according to the instructions defined within the script.

How to Convert a BMS File

Converting a BMS file to another file format or converting other file types to the BMS extension is not a typical scenario. BMS files primarily serve as extraction scripts and are not intended for conversion purposes.

Their role is to facilitate the extraction of data from various file formats rather than being converted themselves. Thus, converting a BMS file to another format may not be applicable or necessary.

Security Considerations: Are “.BMS” Files Safe?

In general, BMS files themselves are not considered a security risk. They are plain text files that contain instructions for data extraction rather than executable code. However, it’s essential to exercise caution when using BMS files obtained from unknown or untrusted sources.

Malicious actors could potentially craft BMS files to exploit vulnerabilities in file extraction tools or manipulate extraction processes to compromise systems. Therefore, it is always recommended to use BMS files from trusted sources or create them yourself.

Format Details for BMS Files

BMS files have a straightforward format. They are plain text files that are typically created and edited using a text editor. The content of a BMS file consists of directives written in the Binary MultiEx Script language, which instruct QuickBMS on how to handle specific file formats and extract data from them.

The BMS language includes commands for seeking, reading, and writing data, as well as performing various operations during the extraction process. Each directive is written on a separate line and follows a specific syntax defined by the BMS language.

Uses and Applications of BMS Files

BMS files find their primary application in extracting assets from video game asset archives. These archives may contain images, audio files, 3D models, textures, scripts, and other data used in video games.

By utilizing BMS files, users can instruct QuickBMS to extract specific assets from these archives without the need for manual extraction or reverse engineering.

This enables modders, game developers, and enthusiasts to access and manipulate game assets for various purposes, such as creating mods, analyzing game resources, or conducting research.
