About .vmu Files
VMU files are plain text files that store data for Hamamatsu uncompressed virtual microscope specimens.
They use the MIME type text/plain to keep content in a human-readable format.
- Main use case: Storing metadata for digital microscope slides.
- Additional uses: Recording configuration details and specimen parameters for research and diagnostic purposes.
- Software support: They can be opened with basic text editors (e.g., Notepad) or specialized digital pathology tools provided by Hamamatsu.
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
How do I open a .vmu file to view the microscope slide?
To view the virtual slide as an image, you must use Hamamatsu NDP.view software. If you simply want to read the metadata or configuration details, you can open the file with any text editor, such as Microsoft Notepad or Apple TextEdit, because it is formatted as plain text.
Can I convert a .vmu file to JPG or TIFF?
You cannot convert the .vmu file directly to an image using a standard converter because it contains text metadata, not pixel data. Instead, open the slide in the NDP.view software and use the Export feature to save specific regions or the entire slide as a TIFF or JPEG image.
Why does my .vmu file only contain text?
The .vmu extension stands for Virtual Microscope Uncompressed, and the file itself acts as a header or descriptor containing metadata about the specimen. The actual image data is often stored in associated raw data files or folders located in the same directory; the .vmu file simply tells the software how to assemble and display that data.
What is the correct MIME type for .vmu files?
These files are classified under the text/plain MIME type. This standard type ensures that web browsers and operating systems recognize the file as human-readable text rather than a binary executable or unknown format.
Why can't I see the image when I move the .vmu file to another computer?
A .vmu file usually depends on external data files to display the microscope image. If you copy only the text file without the accompanying raw data folders or files, the viewer software will not be able to load the slide.
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.
