About .vssm Files

VSSM files are macro-enabled Visio stencil files that store a collection of reusable shapes and symbols for creating diagrams. They follow the Office Open XML format and can include embedded macros for added automation and interactivity.

Their MIME types reveal key aspects of their functionality:


VSSM files are mainly used in Microsoft Visio to supply a palette of standardized symbols for diagrams such as flowcharts, network layouts, and organizational charts. The macro functionality allows these shapes to automate repetitive tasks or perform custom actions when used in diagrams.

They are typically opened, viewed, and edited in Microsoft Visio (2013 or later versions). Other compatible Visio viewers or add-in tools may also support these files.

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.

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.
