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.
Associated MIME types

FAQs
How do I open an .mpp file on Windows?
The primary software for opening .mpp files is Microsoft Project. If you do not have a license for this software, you can use third-party viewers like ProjectLibre, Seavus Project Viewer, or OpenProj to view the Gantt charts and task lists.
Can I open an .mpp file without Microsoft Project?
Yes, there are several alternatives to view and edit these files without purchasing Microsoft Project. Open-source tools like ProjectLibre are popular free options. Additionally, online services like Project Plan 365 allow you to upload and view .mpp files directly in a web browser.
Why is my .mpp file playing audio instead of showing a schedule?
Your file is likely a Musepack Audio file rather than a Microsoft Project file. These files contain high-quality compressed audio and use the MIME type audio/musepack. You can play them using media players like Foobar2000, Winamp, or VLC Media Player.
How can I convert an .mpp file to Excel or PDF?
If you have Microsoft Project installed, you can use the File > Export or Save As feature to convert the project data into Excel (.xlsx) or PDF formats. If you do not have the software, many online file conversion tools can transform the .mpp schedule into a printable PDF.
How do I open .mpp files on a Mac?
Microsoft Project does not have a native macOS application. Mac users typically use compatible software such as Merlin Project, OmniPlan, or Project Plan 365 to import and view .mpp files. Alternatively, running Windows via Parallels or Boot Camp allows you to use the original MS Project software.
What is the correct MIME type for serving .mpp files?
For Microsoft Project files, the standard MIME type is application/vnd.ms-project. However, if you are serving Musepack audio files, you should configure your server to use audio/musepack or audio/x-musepack. You can verify these configurations at mime-type.com.
Are .mpp files safe to open?
Generally, .mpp files are safe data files containing schedules or audio. However, like any file capable of containing macros or scripts (in the context of Office automation), you should be cautious if the file comes from an unknown source. Always scan downloads with antivirus software before opening.
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.
