About .prz Files
PRZ files are presentation files used by Lotus Freelance Show software.
They store slide show data, including text, images, and multimedia elements, in a binary format.
These files use the following MIME types:
- application/vnd.lotus-freelance – Specifically signals usage with Lotus Freelance Show.
- application/octet-stream – Indicates a generic binary file, often used when the exact format is not recognized.
Compatible software includes Lotus Freelance Show and related conversion or presentation tools.
According to FilExt.com, this file type is central to the Lotus Freelance suite and is designed to manage presentation data efficiently.
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 PRZ file?
PRZ files are presentation slides created by Lotus Freelance Graphics, which was part of the IBM Lotus SmartSuite. Similar to Microsoft PowerPoint, these files contain slide layouts, text, graphics, and charts used for business presentations.
How do I open a PRZ file on Windows?
To open a PRZ file natively, you need Lotus Freelance Graphics or the IBM Lotus SmartSuite. Since this software is discontinued, you may need to run it in Compatibility Mode on newer Windows versions or use a virtual machine running Windows XP.
Can Microsoft PowerPoint open PRZ files?
Modern versions of Microsoft PowerPoint (2013 and later) generally do not support opening .prz files. However, older versions of PowerPoint (such as 2003 or 2007) often included a file converter that allowed users to import Lotus Freelance Graphics presentations.
How can I convert a PRZ file to PDF?
If you have access to the original Lotus Freelance Graphics software, the best method is to open the presentation and use a virtual printer to "print" the slides to a PDF file. Without the original software, you may need to use a specialized third-party file conversion service.
What is the correct MIME type for PRZ files?
The specific media type for these files is application/vnd.lotus-freelance. If a server is not configured for this specific legacy format, it may serve the file as application/octet-stream. For more configuration details, visit mime-type.com.
Are PRZ files dangerous?
Like other legacy office document formats, .prz files can theoretically contain malicious code if they include macros or scripts. You should only open PRZ files from trusted sources, especially since modern antivirus software may not actively scan this obsolete format as strictly as modern files.
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.
