About .rxd Files
RXD files are Borland Reflex Database files. They contain structured data in a binary format.
They are used to store tables, records, and database schema details. The MIME type application/octet-stream indicates that they are generic binary files.
- Data Storage: Used to hold relational data such as tables and records.
- Binary Format: Marked with application/octet-stream for non-text data.
- Software Use: Typically accessed with Borland Reflex. Legacy database tools may also support RXD files.
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 .rxd file?
An .rxd file is a database file associated with Borland Reflex (also known as Reflex: The Analyst), a legacy database management system for MS-DOS. It stores structured data, including tables, records, and field definitions, in a binary format.
How can I open an RXD file on a modern computer?
Because Borland Reflex is obsolete software, you typically cannot open these files natively on Windows 10 or 11. To access the data, you may need to run the original Borland Reflex software within a DOS emulator like DOSBox.
Can I convert an RXD file to Excel or CSV?
There are no standard modern converters for the RXD format. The most effective method is to run the original Reflex software in an emulator, export the data to a generic text or ASCII format, and then import that file into Microsoft Excel or Google Sheets.
Why is the MIME type for RXD listed as application/octet-stream?
RXD files are binary files without a widely registered specific media type, so they default to the generic application/octet-stream. This tells the operating system or browser that the file contains arbitrary binary data; more details on this type can be found at mime-type.com.
Can I view the contents of an RXD file using Notepad?
Notepad is not suitable for editing .rxd files because they contain binary code rather than plain text. While opening the file in a text editor might reveal some readable strings (like column headers), saving changes will likely corrupt the file structure.
Are RXD files dangerous?
RXD files are data files, not executable programs, so they are generally safe. However, because they use the generic application/octet-stream MIME type, email servers often treat them with caution. It is always best practice to scan unknown files from legacy sources.
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.
