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 .ppz file?
A .ppz file is a Microsoft PowerPoint Packaged Presentation, historically created by the "Pack and Go" wizard in older versions of PowerPoint. It acts as a compressed container that bundles a presentation with its linked media files (like images and audio) and sometimes a viewer, making it easier to transport between computers.
How do I open a .ppz file on Windows?
You can open .ppz files with Microsoft PowerPoint. Since this is a legacy format, you may need to launch PowerPoint first and use File > Open to locate the file, rather than double-clicking it. Free alternatives like LibreOffice Impress or Apache OpenOffice may also support opening these archives.
How can I convert a .ppz file to a modern .pptx format?
To convert the file, open it in Microsoft PowerPoint, click on the File menu, and select Save As. Choose PowerPoint Presentation (*.pptx) from the file type dropdown list. This updates the internal structure to the modern XML-based standard used by current software.
What is the correct MIME type for serving .ppz files?
PPZ files are typically served with the standard PowerPoint MIME type application/vnd.ms-powerpoint. You may also encounter application/mspowerpoint on older server configurations. For a complete list of related types, visit mime-type.com.
Why can't I view a .ppz file on my mobile device?
Most mobile viewers only support modern formats like .pptx or .pdf. To view a .ppz file on a phone or tablet, you should first convert it to a PDF or a modern PowerPoint file using a desktop computer.
Are .ppz files safe to open?
Like other legacy binary Microsoft Office formats, .ppz files can potentially contain macros or security vulnerabilities. You should only open these files if they come from a trusted source, and consider scanning them with antivirus software before accessing them.
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.
