About .hed Files

HED files are specialized image files used to store header data for the Hi-Eddi format. They contain vital metadata like image dimensions, color depth, and other display parameters.

The MIME type image/x-hi-eddi indicates that these files are part of a niche imaging system. They often work in tandem with companion files that hold the main image data.


Based on information from FilExt.com, HED files are not common in everyday computing and require specific tools for proper use.

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 software can open a .HED file?

You can open .HED files using versatile image viewers like XnView MP or Konvertor. These programs are designed to handle legacy and specialized formats like Hi-Eddi that standard operating system viewers cannot read.

Why can't I see an image when I open a .HED file?

A .HED file is often just a header containing metadata (dimensions, color depth), not the actual pixel data. If the companion data file is missing from the same folder, the software will not be able to reconstruct or display the image.

How do I convert a .HED file to JPG or PNG?

You can use conversion utilities within XnView or Konvertor to save the file as a standard image format. Open the .HED file in the software and use the Save As or Export function to select JPG, PNG, or TIFF.

What is the MIME type associated with .HED files?

The specific MIME type for these files is image/x-hi-eddi. This identifier helps systems recognize the file as part of the Hi-Eddi imaging system. For more configuration details, see image/x-hi-eddi.

Are .HED files dangerous?

Generally, .HED files are simple binary headers containing image parameters and are not executable. However, like any unknown file downloaded from the internet, you should scan it with antivirus software before opening it.

Can I edit a .HED file in Photoshop?

No, Adobe Photoshop does not natively support the Hi-Eddi format. You would first need to convert the file to a supported format like TIFF or PNG using a dedicated converter before editing it in Photoshop.

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.
