Which MIME types are related to file extension ".wtt"?
The .wtt file extension is associated with 2 MIME types:
application/octet-stream, application/x-wtt.
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .wtt Files
WTT files are used as either Write! documents or WorldWide Telescope Tour files.
They rely on different MIME types to define their purpose. One MIME type, application/octet-stream, is used for Write! documents. The other, application/x-wtt, is for WorldWide Telescope Tour files.
- Main Use Case: They either store word processing document data for the Write! application or hold data for guided celestial tours in the WorldWide Telescope software.
- MIME Details: Write! documents use a generic binary MIME type (application/octet-stream), while WorldWide Telescope Tour files use application/x-wtt.
- Software: Open Write! documents with the Write! application. Launch WorldWide Telescope Tour files using software like Microsoft WorldWide Telescope.
- Functionality: Write! documents handle text, images or other document elements. WorldWide Telescope Tour files define a sequence of views, transitions and narration to create an interactive tour.
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 .wtt file?
A .wtt file is primarily associated with two different programs: the Write! distraction-free text editor and the WorldWide Telescope. It either contains a text document with formatting or a guided celestial tour sequence, depending on which software created it.
How do I open a .wtt file created by Write!?
You need to install the Write! application to open these documents natively. Once opened, you can view the text, images, and formatting exactly as the author intended. Since these files sometimes use the generic application/octet-stream MIME type, you may need to manually select the Write! app from your "Open with..." menu.
How do I view a WorldWide Telescope Tour file?
To view a WWT tour, you must have the Microsoft WorldWide Telescope software installed. These files use the MIME type application/x-wtt and contain data for transitions, narration, and camera angles that guide you through a virtual representation of the universe.
Can I convert a .wtt file to PDF or Word?
If the file is a Write! document, yes. Open the file in the Write! editor and use the Export function to save it as .pdf, .docx, .txt, or Markdown. WorldWide Telescope tour files, however, cannot be converted to text documents.
Why does my computer not recognize the .wtt extension?
This usually happens because neither Write! nor WorldWide Telescope is installed. Without the specific software, Windows does not know how to handle the file. You can search mime-type.com to verify the file type or try opening it with a basic text editor like Notepad to inspect the header for clues.
How should I configure my server to host WorldWide Telescope files?
If you are hosting tour files for download or web use, you should configure your web server to associate the .wtt extension with the MIME type application/x-wtt. This ensures browsers and the WWT client handle the file correctly.
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.
