About .rff Files

RFF files are encrypted containers used by the Build Engine.
They are stored as binary data. Their MIME type, application/octet-stream, indicates a generic binary format.

For more details, see the RFF file extension page on FilExt.com.
These files are not meant to be opened by generic editors or media players, as they require the proper decryption process.

Relationship between file extension and MIME type

A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.

File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.

File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs

What is an .rff file?

An .rff file is an encrypted resource container used primarily by video games developed on the Build Engine, most notably Blood by Monolith Productions. These files function similarly to archives, storing game assets like graphics, audio, and level maps in a protected binary format.

How do I open an .rff file?

You cannot open these files with standard software like Notepad or WinRAR because they are encrypted. To view or modify the contents, you need specific modding tools designed for Build Engine games, such as BARF (Blood Archive Resource File) or XWE.

Can I convert .rff files to images or audio?

You generally do not convert the entire .rff file; instead, you extract the specific assets contained within it. Using a tool like WinBarf, you can extract embedded files (such as .wav audio or .art textures) and then edit or convert those individual files using standard media software.

What is the MIME type for .rff files?

RFF files are typically identified as application/octet-stream. This is a generic setting for binary data when a specific type is not registered. You can find more details about this general binary classification at application/octet-stream on mime-type.com.

Is it safe to delete .rff files?

No, you should not delete .rff files if they are located in a game directory. These files contain essential game data, and removing them will likely cause the game to crash or fail to launch entirely.

Why can't I edit .rff files in a text editor?

RFF files contain compiled binary code and encrypted data, which appears as garbled text in editors like Notepad. Editing them directly without proper decryption tools will corrupt the file and render the associated game unplayable.

General FAQ

What is a MIME type?

A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.

MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.

MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.

How do I find the MIME type for a file?

You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.

Why can one extension have multiple MIME types?

Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
