Which MIME types are related to file extension ".adb"?
The .adb file extension is associated with 2 MIME types:
text/x-ada, application/octet-stream.
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .adb Files
ADB files are used for two main purposes based on their MIME types.
They can be text-based Ada source code files when identified as text/x-ada. In this form, they hold Ada programming language code. This code is human-readable and can be edited with text editors like Notepad++ or IDEs such as GNAT Studio.
They can also represent binary data when classified as application/octet-stream. This version is used by some HP Phone/Database/Note database systems and may require special software to view or edit its content.
Key facts include:
- Ada Source Code: Contains the implementation details of Ada programs. It is plain text and works with compilers and development tools.
- HP Database Files: Stores binary information for HP-based applications. It may need proprietary applications to access the data 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 an .adb file used for?
An .adb file is primarily known as an Ada Body file, containing the source code implementation for an Ada program. However, it can also be a legacy database file used by HP 100LX/200LX palmtop organizers. You must determine the file's origin to choose the correct software.
How do I open an .adb file containing source code?
Since Ada body files are plain text, you can view and edit them using any text editor such as Notepad++, Sublime Text, or Visual Studio Code. For development, specialized IDEs like GNAT Studio provide syntax highlighting and compilation tools.
How can I tell if my .adb file is code or a database?
Open the file in a basic text editor like Windows Notepad. If you see readable text with keywords like package body, it is an Ada source file with the MIME type text/x-ada. If the content looks like garbled symbols or random characters, it is likely a binary HP database file identified as application/octet-stream.
How do I compile an .adb file?
To run the code, you need an Ada compiler such as GNAT, which is part of the GCC collection. You typically compile the file using the command line instruction gnatmake filename.adb, provided you also have the corresponding specification (.ads) file.
Can I convert an HP .adb file to Excel or CSV?
Direct conversion is difficult because the HP Appointment Book format is proprietary and obsolete. You would typically need the original HP connectivity software or a virtual machine running the legacy OS to export the data to a text format before importing it into Excel.
What is the correct MIME type for .adb files?
For Ada programming files, the correct media type is text/x-ada. If the file contains binary data, such as the HP database format, it usually defaults to the generic application/octet-stream. You can learn more about configuring these types at mime-type.com.
Why won't my .adb file open in GNAT Studio?
If GNAT Studio cannot open the file, it might be corrupt or it might actually be an HP binary file rather than source code. Additionally, ensure that the matching .ads (specification) file is located in the same directory, as Ada programs often require both files to function correctly.
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.
