About .gtm Files
GTM files are used to store collaboration messages in the Microsoft Groove environment. They carry data such as text messages, commands, and metadata.
The MIME type application/vnd.groove-tool-message designates this file's role in exchanging tool messages within Groove sessions.
- Main Use: Handling and synchronizing messages in a collaborative workspace.
- Content: Contains communication data and session details.
- Software: Typically opened with Microsoft Office Groove or related collaboration applications.
- Additional Uses: May serve as logs or transaction records in shared team environments.
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 GTM file?
A GTM file is a data file associated with Microsoft Groove (later rebranded as SharePoint Workspace). It stores "tool messages" which contain commands, text, and synchronization data used to coordinate activities within a shared collaborative workspace.
How do I open a GTM file?
To open a GTM file, you typically need Microsoft Office Groove 2007 or Microsoft SharePoint Workspace 2010. Since this software is discontinued, opening these files on modern operating systems like Windows 10 or 11 can be difficult without access to legacy Office installers.
What is the correct MIME type for GTM files?
The specific MIME type used for these files is application/vnd.groove-tool-message. This identifier helps the operating system and servers understand that the file belongs to the Groove environment. You can verify MIME details at mime-type.com.
Can I convert a GTM file to PDF or Word?
Direct conversion is rarely possible because .gtm files contain internal application data and commands rather than standard document text. To view the information inside, you generally must load the file into the original Microsoft Groove interface and copy the content manually.
Why can't I open my GTM file on a new computer?
Modern computers often lack the specific legacy software required to interpret the application/vnd.groove-tool-message format. Because Microsoft Groove has been replaced by tools like OneDrive and Teams, the file association for .gtm is likely missing from your system registry.
Are GTM files still in use today?
They are considered a legacy format. While some organizations running older, isolated versions of Microsoft Office might still use Groove, most users have migrated to modern cloud collaboration platforms, making .gtm files rare in current environments.
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.
