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 .hiv file?
A .hiv file is a Windows Registry Hive file that stores system or user configuration data in a binary format. Unlike standard folders, these files contain keys, subkeys, and values that the Windows operating system loads to manage hardware, software, and user preferences.
How do I open a .hiv file?
You cannot open a .hiv file by double-clicking it; you must use the Windows Registry Editor (regedit.exe). Open Regedit, highlight a key (such as HKEY_LOCAL_MACHINE), go to File > Load Hive, and select your file to mount it and view its contents.
Can I view .hiv files in Notepad?
No, .hiv files are binary files, meaning they do not contain human-readable text. Opening one in a text editor like Notepad will display unreadable symbols; you need a dedicated tool like the Registry Editor or a digital forensics viewer to interpret the data.
Is it safe to delete or rename .hiv files?
Generally, no. Files like SAM, SECURITY, SOFTWARE, and SYSTEM located in C:\Windows\System32\config are active .hiv files essential for Windows to boot. Deleting or renaming them can cause a complete system failure.
How can I convert a .hiv file to a .reg file?
To convert the data, you must first load the hive into the Windows Registry Editor. Once loaded, right-click the temporary key you created, select Export, and save the file with the .reg extension. This creates a text-based version of the registry keys.
What is the difference between .hiv and .reg files?
A .hiv file is the actual binary database file stored on the hard drive that Windows uses directly. A .reg file is a text-based export used for sharing tweaks, backing up specific keys, or manually importing settings into the registry.
What is the MIME type for .hiv files?

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.
