About .pzx Files
PZX files are Perfect ZX Tape files used to store digital images of ZX Spectrum cassette tapes.
They are binary files with the MIME type application/octet-stream.
- They capture the original tape data including sound pulses and data signals.
- They are used with emulators to run or preserve ZX Spectrum software and games.
- They require specialized tools or software like ZX Spectrum emulators to be played or converted.
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 .pzx file?
A .pzx file is a disk image format known as Perfect ZX Tape, designed to preserve software for the Sinclair ZX Spectrum. Unlike simpler formats, it captures the exact magnetic pulse sequences of the original cassette tape, ensuring that copy-protected games and custom loaders work correctly in emulation.
How do I open a .pzx file?
You need a ZX Spectrum emulator to run these files. Popular emulators that support the .pzx format include Fuse (Free Unix Spectrum Emulator), Spectaculator, and ZEsarUX. In the emulator, look for an option to "Load Tape" or "Insert Cassette" and select your file.
What is the difference between .pzx, .tzx, and .tap?
While .tap files only store standard data blocks, .pzx files record the raw pulse timing required for high-fidelity preservation, similar to .tzx. However, the .pzx format was created to be simpler and easier for developers to implement than .tzx while maintaining 100% accuracy for complex loading schemes.
Can I convert a .pzx file to audio?
Yes, because .pzx files contain raw pulse data, they can be converted to standard audio formats like WAV. Tools like tape2wav or built-in export features in emulators like Fuse allow you to create an audio file that can be played back to a real ZX Spectrum hardware via an audio cable.
What MIME type is used for PZX files?
There is no specific registered MIME type for PZX files, so they are generally served as generic binary data using application/octet-stream. Web administrators hosting these files should ensure the server is configured to force a download rather than attempting to display the binary content in the browser.
Why won't my emulator load the .pzx file?
The .pzx format is a relatively newer standard compared to .tzx or .tap. If your emulator fails to open the file, it may be outdated or lack support for this specific format. Try updating to the latest version of Fuse or checking the emulator's documentation for supported tape formats.
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.
