About .cht Files
CHT files are binary files used to store chart data generated by Harvard Graphics Chart (vA.01).
They use the MIME type application/octet-stream, which means they are not plain text and need specific software to interpret their structure.
- Main use: They hold chart and graph design information for visual data representation.
- Other uses: They are sometimes used to archive legacy chart designs that may be converted or edited with compatible software.
- Software support: They are primarily opened with Harvard Graphics. Legacy viewers or conversion tools might also work with these 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 a .cht file?
A .cht file is typically a binary data file containing chart or graph information created by Harvard Graphics, specifically older versions like Chart vA.01. It stores the visual design and numerical data required to render a presentation chart.
How do I open a .cht file on Windows?
You need the original Harvard Graphics software to open these files correctly. Because this is a legacy format, modern office suites like Microsoft Excel or PowerPoint generally do not support opening .cht files directly.
Why does my text editor show garbled text when opening a .cht file?
The file contains binary data rather than plain text, often identified by the MIME type application/octet-stream. Text editors like Notepad cannot interpret the binary structure of the chart, so they display unreadable symbols.
Are there other uses for the .cht extension?
Yes, the .cht extension is frequently used for cheat files in video game emulators (such as ZSNES or Snes9x). If your file is related to gaming rather than business presentations, it is likely a text-based cheat code list and not a Harvard Graphics chart.
How can I convert a .cht file to a modern image format?
Conversion usually requires opening the file in Harvard Graphics and using the software's export or print function. You can try printing the chart to a virtual PDF printer to save it as a PDF, which can then be converted to JPG or PNG.
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.
