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 .tbk file?
A .tbk file is a multimedia project created by Asymetrix ToolBook (later acquired by SumTotal Systems). These files are typically used for e-learning courses, interactive quizzes, and digital training manuals that combine text, images, and scripting.
How do I open a TBK file?
You need SumTotal ToolBook (specifically the Instructor or Assistant versions) or the ToolBook Neuron browser plugin to view these files. Because the software is considered legacy, you may need to run it in 'Compatibility Mode' on modern versions of Windows.
Can I convert a TBK file to HTML or PDF?
Yes, but you usually need the original ToolBook authoring software to do so. Later versions of ToolBook include an option to export projects to DHTML or HTML5 for web viewing; converting directly to PDF is often not possible without losing the interactive elements.
What is the MIME type for TBK files?
The standard MIME type for these files is application/toolbook. This identifier helps web servers and browsers understand that the file requires a specific plugin or helper application, which you can read more about on mime-type.com.
Why can't I open my TBK file?
If you do not have ToolBook installed, your computer will not recognize the file. Additionally, the .tbk extension is sometimes used by the email client The Bat! for backup archives; if the file isn't an e-learning course, try opening it with The Bat!'s restore feature.
Are TBK files safe to open?
Generally yes, but like any file containing scripts or macros, they can theoretically harbor malicious code. You should only open .tbk files from trusted sources or educational institutions.
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.
