About .rbfrm Files
RBFRM files are used to store the definition of forms and windows in the REALbasic development environment. They are saved in a plain text format, which means you can open and edit them with simple text editors or within the REALbasic/Xojo IDE.
- Main Use: They hold the layout and design information for user interfaces.
- MIME Type: text/plain, emphasizing their readability and ease of editing.
- Key Fact: They define how windows and controls appear and behave in an application.
- Software Support: Designed for REALbasic/Xojo; basic text editors can also view them.
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 .rbfrm file?
An .rbfrm file is a form definition file used by the REALbasic development environment, which is now known as Xojo. It stores the layout, properties, and code associated with a specific window or GUI form in a human-readable text format.
How do I open an .rbfrm file?
You should open these files using the Xojo IDE (formerly REALbasic) to interact with the visual form designer. Since the file contains plain text, you can also view its contents using standard text editors like Notepad on Windows or TextEdit on macOS.
What is the MIME type for .rbfrm files?
The standard MIME type for these files is text/plain because they consist entirely of readable text characters. You can learn more about text-based media types at mime-type.com.
Can I convert old .rbfrm files to modern Xojo formats?
Yes, modern versions of Xojo are generally backward compatible and can import legacy .rbfrm files. Once imported, you can save the project in newer formats, such as the Xojo binary format or the Xojo XML project format.
Why can I read the content of an .rbfrm file in Notepad?
REALbasic designed the .rbfrm format as plain text to facilitate easier debugging and compatibility with version control systems. This allows developers to see the raw definition of controls and properties without needing a hex editor.
Is it safe to edit an .rbfrm file manually?
While it is possible to edit the text manually, it is risky because incorrect syntax can prevent the file from loading in the IDE. It is highly recommended to use the Xojo environment for making changes to the visual layout or logic.
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.
