About .wr1 Files
WR1 files are Lotus Symphony Worksheet V1 files used to store spreadsheet data. They carry the MIME type application/vnd.lotus-1-2-3 that is linked with Lotus spreadsheet formats.
- Main Use: Designed for storing grid-based data, formulas, and cell formatting.
- Software Compatibility: Open and edit these files with applications like Lotus Symphony or Lotus 1-2-3.
- Legacy Format: Represents an older file type still used in certain legacy environments.
These files arrange data in rows and columns and often include basic calculation functions.
Based on information from FilExt.com, WR1 files are most useful when accessing or converting older Lotus spreadsheet documents.
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 WR1 file?
A WR1 file is a spreadsheet created by Lotus Symphony (Version 1), a legacy integrated software suite. It contains data organized in rows and columns, formulas, and formatting, similar to modern Excel files. These files are associated with the MIME type application/vnd.lotus-1-2-3.
How do I open a WR1 file on a modern computer?
Because this is an older format, you may need legacy software like Lotus 1-2-3 or Corel Quattro Pro (part of WordPerfect Office). Some older versions of Microsoft Excel may also be able to import these files, but support has been removed in recent editions.
Can Microsoft Excel open WR1 files?
Modern versions of Excel (2007 and later) usually cannot open WR1 files directly due to security changes and dropped legacy filters. You generally need to use an older version of Excel (like Excel 97 or 2003) or a dedicated file converter to change it to .xls or .xlsx format first.
How can I convert a WR1 file to CSV or Excel?
The most reliable method is to open the file in a compatible program like Lotus 1-2-3 or Quattro Pro and use the "Save As" feature to select .csv or .xls. If you do not have this software, look for specialized legacy file conversion utilities that handle application/vnd.lotus-1-2-3 types.
Why does the WR1 file look like gibberish in Notepad?
WR1 files are binary files, not plain text. If you open them in a text editor like Notepad, you will see unintelligible characters because the editor cannot interpret the binary spreadsheet structure. You must use a spreadsheet application to view the data.
What is the MIME type for WR1 files?
The standard MIME type used for Lotus spreadsheet files, including WR1, is application/vnd.lotus-1-2-3. This identifier helps systems recognize that the file belongs to the Lotus family of spreadsheet applications.
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.
