About .wq2 Files
WQ2 files are a legacy binary spreadsheet format used by Quattro Pro on DOS, version 5.
They use the MIME types application/octet-stream and application/x-quattro-pro to indicate that they contain binary data specific to Quattro Pro spreadsheets.
These files store data like numbers, text, and formulas in a compact structure.
- Main use: Handling spreadsheets for business and data management in legacy DOS environments.
- Software: Opened primarily by Corel Quattro Pro and specialized conversion tools on modern systems.
- Key Fact: They are part of an older generation of file formats and may require conversion for current use.
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 .wq2 file?
A .wq2 file is a spreadsheet created by Borland Quattro Pro version 5 for DOS. It is a legacy binary format that stores data in rows and columns, including formulas and text, similar to modern Excel files but designed for older operating systems.
How can I open a .wq2 file on Windows 10 or 11?
You can open these files using Corel Quattro Pro, which is included in the Corel WordPerfect Office suite. Alternatively, you can use a universal file viewer like File Viewer Plus, or run the original DOS software using an emulator like DOSBox.
Can Microsoft Excel open .wq2 files?
Modern versions of Microsoft Excel (2013 and later) generally do not support opening legacy DOS spreadsheet formats like .wq2 directly. You may need to use an older version of Excel (such as Excel 97 or 2003) or convert the file using Corel Quattro Pro first.
How do I convert a .wq2 file to CSV or XLSX?
The most reliable method is to open the file in Corel Quattro Pro and use the Save As feature to select a modern format like .xlsx or .csv. There are also specialized online legacy file conversion tools that may handle this format.
What is the MIME type for .wq2 files?
These files are often identified by the generic binary type application/octet-stream on web servers. However, the specific type application/x-quattro-pro is also used to explicitly denote Quattro Pro spreadsheets. You can verify these types at mime-type.com.
Why does the file look like garbled text when opened in Notepad?
The .wq2 format is a binary file, not a plain text file. Opening it in a text editor like Notepad displays the raw binary code as unintelligible characters; you must use compatible spreadsheet software to interpret the data structure correctly.
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.
