About .hpkg Files
HPKG files are binary package files used on the Haiku operating system.
They are designed to install and update software efficiently.
They are known as Haiku Delta Packages because they can deliver only the changes needed in an update.
- Main use case: Deploying software and system updates in Haiku OS.
- MIME type: They use application/octet-stream, which is a generic type for binary data.
- Content: They bundle executables, libraries, and metadata for proper installation.
- Management: Handled by Haiku's Package Manager and related system tools.
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 HPKG file?
An HPKG file is a software package used by the Haiku operating system. It contains compiled programs, libraries, and metadata required to install or update applications. Unlike traditional installers, these packages are mounted virtually by the OS rather than extracted to the hard drive.
How do I install an HPKG file on Haiku?
To install an HPKG file, simply move or copy the file into the ~/config/packages directory (for the current user) or /system/packages (for all users). The Haiku Package Management system automatically detects the file and mounts it, making the contained software immediately available.
Can I open HPKG files on Windows or macOS?
Generally, no, as HPKG files are specific to the Haiku operating system. While you might be able to inspect the binary data using a hex editor or generic archive tools that support custom formats, the executable software inside will not run on Windows or macOS.
How can I extract the contents of an HPKG file?
On a Haiku system, you can use the package command-line tool. Running package extract my_software.hpkg will unpack the contents into the current directory. This is useful for inspecting files without globally installing the package.
What is the correct MIME type for HPKG files?
These files are binary packages and typically use the generic MIME type application/octet-stream. Since the format is specific to Haiku, web servers usually treat them as generic binary data streams. You can learn more about this type at application/octet-stream.
Are HPKG files compressed like ZIP files?
Yes, HPKG files are compressed, but they use a specialized format optimized for random access and virtual mounting. They are not standard ZIP archives, so standard unzip tools will likely fail to open them correctly.
How do I create my own HPKG file?
Developers can create packages using the package create command in the Haiku terminal. You must provide a .package-info file containing metadata (name, version, architecture) along with the files you wish to bundle.
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.
