What is MIME type "application/vnd.ms-visio.template.macroenabled.12"?

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

application/vnd.ms-visio.template.macroenabled.12 is a MIME type used for a Microsoft Visio template file that supports macros.

This file is designed as a starting point for creating Visio diagrams. It contains pre-set shapes, formatting, and even embedded macros to automate tasks during diagram creation.

Its main use is to ensure consistency and efficiency when building complex diagrams. The macros can simplify repetitive tasks and enforce standard practices in diagram design.

Template Creation: Provides a ready-to-use framework for new diagrams.
Automation: Contains macros that run automated routines to speed up repetitive processes.
Standardization: Helps maintain uniform design and formatting across projects.

Files of this type have the extension VSTM. This association lets web servers and applications identify and process the file correctly when shared or stored.

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.
