About .ocd Files
OCD files are OCAD map files that hold detailed cartographic data. They use the application/octet-stream MIME type, which indicates a generic binary format.
These files are mainly used in mapping for orienteering and related tasks. They store route details, control points, contours, and other map elements. They are created and edited with specialized mapping software like OCAD.
- Main use: Designing and storing orienteering maps
- Technical detail: Binary file format as shown by its MIME type
- Software: Opened with OCAD and similar mapping tools
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
How do I open an OCD file?
You can open .ocd files using OCAD, the proprietary software designed for cartography and orienteering. For a free alternative, you can use OpenOrienteering Mapper, an open-source program available for Windows, macOS, and Linux that supports this format.
Can I convert an OCD file to PDF?
Yes, you can convert an .ocd file to PDF using the Export feature within the OCAD software or OpenOrienteering Mapper. This is the standard method for preparing orienteering maps for printing or digital distribution.
Is there a free viewer for OCD files?
Yes, OpenOrienteering Mapper acts as both a free editor and viewer for .ocd files. Additionally, OCAD offers a free "OCAD Viewer" edition that allows users to view and print maps without editing capabilities.
What is the correct MIME type for serving OCD files?
Because .ocd files are binary, they typically use the generic application/octet-stream MIME type. You can find more details about generic binary streams and server configurations at mime-type.com.
Why can't I read the OCD file in Notepad?
OCD files store complex cartographic vector data in a binary format, not plain text. Opening the file in a text editor like Notepad will result in unreadable characters; you must use specialized mapping software to interpret the data.
Can I open OCD files on a smartphone?
Directly opening .ocd files on mobile is difficult without specific apps like OOMapper (available on Android). It is usually easier to convert the map to a standard image format or PDF on a computer before viewing it on a mobile device.
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.
