Which MIME types are related to file extension ".xex"?
The .xex file extension is associated with 1 MIME types:
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .xex Files
XEX files are executable programs for Atari XE systems. They are stored as binary data with the MIME type application/octet-stream.
They contain machine code that runs directly on Atari hardware or emulators. This file type is often used for homebrew software, games, and demos on Atari computers.
- Main use: Running Atari XE programs.
- Binary Format: Uses the generic MIME type to indicate non-text, machine-readable data.
- Software: Open these files with Atari emulators like Altirra or Atari800, or on original Atari hardware.
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 an .xex file?
An .xex file is an executable program designed for Atari 8-bit computers, such as the Atari 65XE or 130XE. These files contain compiled machine code used for running games, demos, and homebrew software directly on Atari hardware or through emulation.
How do I open an .xex file on my PC?
You cannot open these files directly in Windows or macOS; you must use an Atari emulator. Popular emulators include Altirra (for Windows) and Atari800 (cross-platform), which allow you to load and run the executable as if you were using the original computer.
What is the MIME type for .xex files?
Because .xex files contain raw binary data without a specific standard header recognized by web browsers, they typically use the generic MIME type application/octet-stream. This instructs the system to treat the file as a downloadable binary rather than attempting to display it.
Can I convert an .xex file to an .atr disk image?
Yes, utilities exist to place standalone executable files onto a virtual floppy disk image (.atr). Tools like Dir2Atr allow you to create a bootable disk image containing your .xex game, which can be useful for emulators that prefer disk-based loading.
Why does my text editor show garbage when I open an .xex file?
These are binary files containing machine instructions, not human-readable text. Opening them in a text editor like Notepad will display random symbols and characters; to view the contents properly, you need a Hex Editor or a disassembler compatible with the MOS 6502 processor.
Are .xex files used by consoles other than Atari?
Yes, the Xbox 360 also uses the .xex extension for its executable files (Xbox Executable). These are completely different formats; an Xbox 360 .xex file will not run on an Atari emulator, and vice versa.
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.
