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 .sgl file?
An .sgl file is primarily a StarOffice Master Document (or Global Document) used to combine multiple individual documents into one large project. It is a legacy binary format originally created by StarDivision and is compatible with modern suites like Apache OpenOffice and LibreOffice.
How do I open an .sgl file on my computer?
You can open .sgl files using free, open-source office suites. Download and install LibreOffice or Apache OpenOffice, open the main Writer application, and use the File > Open command to locate and view your document.
Can I convert an .sgl file to Microsoft Word or PDF?
Yes, after opening the file in LibreOffice Writer, you can convert it. Select File > Save As to save it as a Microsoft Word document (.docx) or use File > Export as PDF to create a portable version.
Why won't Microsoft Word open my .sgl file?
Microsoft Word does not natively support legacy StarOffice binary formats. To access the content, you must first open the file in LibreOffice or OpenOffice and save it in a format Word understands, such as .doc or .docx.
What is the correct MIME type for .sgl files?
The specific MIME type for StarOffice Writer Global documents is application/vnd.stardivision.writer-global. However, the extension is sometimes associated with other StarDivision types found on mime-type.com, such as application/vnd.stardivision.writer.
Are .sgl files dangerous to open?
Generally, .sgl files are safe document containers, but like any office file, they could theoretically contain malicious macros. Always ensure you trust the source of the file and consider scanning it with antivirus software before opening it in OpenOffice or LibreOffice.
Is the .sgl format still actively used?
No, .sgl is considered a legacy format and has been largely replaced by the OpenDocument standard (specifically .odm for master documents). It is recommended to convert these files to modern formats to ensure long-term accessibility.
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.
