A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .hdz Files
HDZ files are binary files used in the KeyShot environment.
They carry essential data needed for 3D rendering projects. The MIME type application/octet-stream tells you that the file is a generic binary file, not plain text.
- Primary Use: Packaging project settings for KeyShot.
- Content: They may include material libraries, lighting setups, camera configurations, and other scene details.
- Software: Open or edit these files only with programs like KeyShot.
- Data Transfer: They enable easy sharing of complex 3D environment data.
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 .hdz file?
An .hdz file is a compressed environment file used by Luxion KeyShot, a popular 3D rendering and animation software. These files typically contain High Dynamic Range (HDR) lighting information and background settings packaged specifically for use within the KeyShot library.
How do I open an .hdz file?
You can open .hdz files exclusively with Luxion KeyShot. To use the file, you generally drag and drop it into the KeyShot interface or import it via the software's Environment library tab to apply the lighting and background settings to your 3D scene.
Can I convert an .hdz file to .hdr or .exr?
Direct conversion is difficult without the native software because .hdz is a proprietary, compressed format. To convert it, you typically need to open the file in KeyShot and then export the environment information as a standard .hdr or .exr file for use in other applications like Photoshop or Blender.
Why does my computer identify the file as application/octet-stream?
This occurs because the .hdz format is a binary file without a specific standard registration in many operating systems. The MIME type application/octet-stream serves as a generic placeholder for binary data that requires a specific application (KeyShot) to interpret the byte stream correctly.
Can I edit .hdz files in Adobe Photoshop?
No, Adobe Photoshop cannot natively open or edit .hdz files. While Photoshop supports standard high-dynamic-range formats like Radiance HDR or OpenEXR, the .hdz extension is specific to KeyShot's internal compression and file structure.
Are .hdz files safe to open?
Generally, yes, .hdz files are safe data files containing image and lighting parameters. However, because they are binary files often labeled as application/octet-stream, you should always ensure they come from a trusted source before downloading or importing them into your software.
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.
