About .neo Files
NEO files are image files saved in the NEOchrome format.
They use the MIME types image/x-neo and image/x-neochrome to define how software reads the file data.
- Image Storage: They hold visual data such as digital photos or graphics.
- Specialized Applications: They are used with programs built around the NEOchrome engine.
- Technical Processing: The MIME types help compatible viewers or editors process the file correctly.
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 .neo file?
A .neo file is a raster image created by NEOchrome, a classic paint program originally designed for the Atari ST computer system. These files store low-resolution graphics and color palette data specific to that hardware era.
How do I open a .neo file on Windows or Mac?
You cannot use standard photo viewers; instead, you need multi-format image viewers like XnView MP, IrfanView, or RECOIL (Retro Computer Image Library). These programs are designed to decode legacy formats like image/x-neochrome.
Can I convert .neo files to JPG or PNG?
Yes, you can convert them using tools like XnConvert or by opening the file in IrfanView and selecting Save As. Converting to PNG is recommended to preserve the pixel art quality without compression artifacts.
Why won't Adobe Photoshop open my .neo file?
Adobe Photoshop does not natively support the Atari NEOchrome format. To edit the image in Photoshop, you must first convert it to a standard format like BMP, TIFF, or PNG using a dedicated file converter.
What is the MIME type for .neo files?
The standard MIME types associated with this format are image/x-neo and image/x-neochrome. These identifiers tell systems that the file contains NEOchrome image data; see mime-type.com for more on image media types.
Is a .neo file a virus?
No, a .neo file is typically just a static image file and is not executable. However, as with any email attachment or download, you should scan unknown files with antivirus software before opening 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.
