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 an XLR file?
An XLR file is a spreadsheet created by Microsoft Works, a productivity suite that has since been discontinued. It stores data in rows and columns similar to Microsoft Excel but uses a different file structure specific to the Works Spreadsheet application.
How can I open an XLR file in Microsoft Excel?
Modern versions of Excel (2013 and later) often cannot open .xlr files directly. To open them, you may need to use a file converter or open the file in LibreOffice Calc, which maintains better backward compatibility, and then save it as an Excel file (.xlsx).
How do I convert an XLR file to PDF or XLSX?
The most reliable method is to open the file in LibreOffice or an older version of Microsoft Works and use the Save As or Export function to select .xlsx or .pdf. Alternatively, various online file conversion tools support uploading .xlr files and downloading them in modern formats.
What is the MIME type for XLR files?
XLR files are associated with the MIME type application/x-tika-msworks-spreadsheet. For more details on configuration and handling, you can visit mime-type.com.
Why can't I open my old XLR files on Windows 10 or 11?
Microsoft discontinued the Works suite, and the necessary file filters are not included in standard Windows 10 or 11 installations. You must install third-party software like LibreOffice or Apache OpenOffice to view or edit these legacy documents.
Are XLR files the same as XLS files?
No, although both are spreadsheets. .xls is the legacy format for Microsoft Excel, while .xlr is the format for Microsoft Works. While they perform similar functions, the internal data structure is different, and they are not automatically interchangeable without conversion.
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.
