About .wkq Files
WKQ files are legacy spreadsheet files made for DOS systems.
They were created using Quattro Pro, an early spreadsheet program. The files hold table data, formulas, and formatting details.
MIME-type details: Versions 1–4 use application/x-quattro-pro, while version 5 is identified as application/octet-stream.
- Main use: Running spreadsheet tasks on DOS systems.
- Additional use: Legacy document management and data extractions.
- Software support: They are best opened with the original Quattro Pro for DOS or compatible conversion tools. Modern suites may require file converters.
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 .wkq file?
A .wkq file is a legacy spreadsheet file created by the DOS version of Borland Quattro Pro. It contains rows and columns of data, formulas, and basic formatting used in early computing environments.
How can I open a .wkq file on Windows 10 or 11?
Most modern software cannot open these files directly. You may try using Corel WordPerfect Office (which includes the modern Quattro Pro) or run the original DOS software using an emulator like DOSBox.
Can Microsoft Excel open .wkq files?
Modern versions of Excel generally do not support .wkq files. You might be able to open them with very old versions of Excel (like Excel 97 or 2003) or by converting the file to a format like .csv or .xls first.
How do I convert a .wkq file to Excel format?
You will need a specialized file conversion tool or a legacy spreadsheet viewer that supports DOS formats. Once opened in a compatible viewer, you can usually Save As or Export the data to CSV, which Excel can read easily.
What is the MIME type for .wkq files?
These files are typically identified as application/x-quattro-pro for versions 1–4. However, due to their age, they are often detected generically as application/octet-stream. You can learn more about these types at mime-type.com.
Is .wkq the same as .wb1 or .qpw?
No, .wkq is specifically for the DOS versions of Quattro Pro. Extensions like .wb1, .wb2, and .qpw are associated with the Windows versions of the software, which use different internal file structures.
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.
