About .ch3 Files
CH3 files are binary files used by Harvard Graphics Chart (v3.x). They carry chart data and instructions in a format that is not plain text.
Key Facts:
- Main Use Case: Storing chart data for Harvard Graphics software.
- MIME Type: Uses application/octet-stream as its identifier.
- Software: Open or edit these files within Harvard Graphics (v3.x) platforms.
- Technical Note: The binary format means the data is structured for machine reading rather than human viewing.
Based on information from FilExt.com, CH3 files are designed specifically for charting in Harvard Graphics applications and are not typically used in other software environments.
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 a .ch3 file on a modern computer?
Because .ch3 files are legacy charts from Harvard Graphics 3.x, opening them usually requires the original software running inside a DOS emulator like DOSBox. In some cases, older versions of Corel Presentations may be able to import the file.
Can I convert a .ch3 file to Excel or PDF?
Direct conversion is difficult without the original Harvard Graphics application. If you can open the file in an emulator, you can try to "print" to a file or take a screenshot to save it as an image; modern converters rarely support this specific format.
Why does my .ch3 file look like garbage text in Notepad?
The .ch3 format is a binary file, meaning it stores data in machine-readable code rather than human-readable text. Opening it in a text editor displays the raw data bytes, which look like random characters.
What is the MIME type for .ch3 files?
Since this is a proprietary, non-web format, it typically defaults to the generic binary MIME type application/octet-stream. For more details on how generic binary streams are handled, visit mime-type.com.
Is the .ch3 format compatible with Mac or Linux?
Not natively. Since Harvard Graphics was primarily a DOS/Windows application, Mac and Linux users must use virtualization software or a DOS emulator to run the environment necessary to view these files.
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.
