A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .fcd Files
FCD files are plain text documents that store FidoCAD drawing instructions. They use the MIME type text/plain, meaning you can view their content in any text editor, though specialized software is needed to render the graphical output.
- Main Use: They record vector drawing instructions for CAD representations.
- File Nature: Being plain text, the file is human-readable and editable.
- Software Compatibility: FidoCAD is the primary tool to open, view, and edit these files. Other text editors may show the raw code.
- Legacy & Niche Applications: Often found in environments linked to FidoNet and similar legacy communities.
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 FCD file?
An .fcd file is a plain text document containing vector drawing instructions created by FidoCAD. These files are primarily used to store electronic schematics and technical drawings in a lightweight, code-based format.
How do I open an FCD file?
To view the rendered drawing, you should use FidoCAD or the modern, cross-platform version known as FidoCadJ. If you only need to view the code structure, any text editor like Notepad or TextEdit will work because the file uses the text/plain MIME type.
Can I convert an FCD file to an image or PDF?
Yes, you can export FCD drawings to common formats using FidoCadJ. The software allows you to save the vector drawing as a PDF, SVG, or raster image (like PNG or JPG) for easy sharing.
Why does my text editor show code instead of a drawing?
FCD files store data as raw text commands rather than binary image data. Your text editor correctly identifies the MIME type as text/plain and displays the drawing instructions (coordinates and shapes) instead of rendering the visual graphic.
Is FidoCAD compatible with macOS and Linux?
Yes, via FidoCadJ. Since FidoCadJ is written in Java, it runs on any operating system that supports the Java Runtime Environment, including Windows, macOS, and Linux.
What if my FCD file contains unreadable characters?
If opening the file in a text editor reveals garbled binary data instead of readable text, you might have a Virtual CD file (by FarStone) instead of a FidoCAD drawing. These are disk images and require virtualization software like VirtualDrive to mount.
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.
