What is MIME type "image/x-3ds"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

image/x-3ds is a MIME type used for 3D model files. It stores mesh data, textures, and light mapping information that help render 3D objects in applications.
This type is common in computer graphics and design. It supports file exchange in programs that work with 3D scenes.

Main use case: Viewing and editing 3D models in software like 3D Studio and similar applications.
Other uses: Importing models into game engines, simulations, or further design work.
Key fact: It ensures compatibility when moving files between different 3D design programs.

Typical files include those with the extension 3DS and project files like MAX.

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 are multiple MIME types listed for one extension?

Different applications and historical conventions may use alternative MIME identifiers for the same kind of file. Showing them all helps ensure compatibility across systems.
