Which MIME types are related to file extension ".vsdm"?
The .vsdm file extension is associated with 3 MIME types:
application/vnd.ms-visio.drawing.macroenabled.12, application/vnd.ms-visio.drawing.macroenabled.main+xml, application/vnd.visio.
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .vsdm Files
VSDM files are a macro-enabled diagram drawing format developed for use with Microsoft Visio.
They are based on the Office Open XML standard. This means the file structure is rich with XML data and supports embedded macros for automation and custom tasks.
Key facts about VSDM files include:
- Diagram Creation: They store complex diagrams like flow charts, organizational charts, and network layouts.
- Macro-Enabled: They can run automated scripts to streamline repetitive tasks within the drawing.
- XML-Based: The format allows easier integration and data manipulation with other Office Open XML files.
Based on information from FilExt.com, VSDM files are ideal for professionals needing advanced visual diagramming with integrated automation features.
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 a VSDM file?
A VSDM file is a macro-enabled drawing created by Microsoft Visio. Unlike the standard .vsdx format, VSDM files contain embedded Visual Basic for Applications (VBA) macros used to automate tasks within the diagram. They utilize the Open XML standard to store flowcharts, organizational charts, and other technical diagrams.
How do I open a VSDM file on Windows?
The best way to open and edit a VSDM file is using Microsoft Visio (2013 or later). If you only need to view the file without editing, you can use the free Microsoft Visio Viewer or open the file in Microsoft Edge if the viewer extension is installed. LibreOffice Draw can also open these files, though formatting may shift and macros will not run.
What is the difference between VSDX and VSDM?
The primary difference is the ability to store macros. VSDX files are standard Visio drawings that cannot execute code, making them safer for general sharing. VSDM files are explicitly designed to support VBA macros for automation; consequently, Visio usually prompts for security permission before running the scripts inside a VSDM file.
Are VSDM files safe to open?
Because VSDM files contain executable macros, they can potentially harbor malware or viruses. You should only open VSDM files sent from trusted sources. When you open the file in Visio, the software will typically display a security warning asking if you want to enable the content; keep macros disabled if you are unsure of the file's origin.
Can I convert a VSDM file to PDF?
Yes, you can easily convert a VSDM file to PDF within Microsoft Visio. Go to File > Save As or File > Export and select PDF as the output format. This flattens the diagram into a document that can be viewed on any device, but the interactive macros will no longer function.
Can I view VSDM files on a Mac?
Microsoft Visio does not have a native desktop application for macOS, but you can view VSDM files using Visio for the web in your browser. Alternatively, third-party diagramming tools like Lucidchart or OmniGraffle can often import VSDM files, although specific macro functionality is usually lost during the import process.
What is the MIME type for VSDM files?
The specific MIME type for VSDM files is application/vnd.ms-visio.drawing.macroenabled.12. This identifies the file to web servers and email clients as a macro-enabled Office Open XML drawing. For more technical details on configuration, you can look up application/vnd.ms-visio.drawing.macroenabled.12.
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.
