What is MIME type "model/vnd.gtw"?

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

model/vnd.gtw is a vendor-specific MIME type. It belongs to the model category that holds data for 3D models.
Files with this type, typically ending in GTW, carry structured information about three-dimensional objects.
Key facts and use cases:

Used for storing geometric data and spatial coordinates.
Holds details like dimensions and model attributes for visualization.
Works with specialized software that interprets its proprietary structure.
May support simulation, design, or rendering processes that require 3D data.

Because it is vendor-specific, support is limited to software designed to process these files. Additional details are often found in vendor documentation or through the IANA media type registry.

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.
