About .sdw Files

SDW files are binary documents created by the StarOffice suite for word processing.

They hold formatted text, images, and embedded objects. They use MIME types like application/vnd.stardivision.writer and application/x-starwriter to signal that they are designed for document editing.

These files are part of a family of formats used by StarOffice. Other MIME types in the group include:


In some cases, an SDW file can be seen with a text/plain MIME type relating to an ESRI World File used in mapping, or as application/octet-stream for an AmiDraw Drawing variant.

SDW files are best opened with StarOffice Writer. They are also supported by alternatives such as Apache OpenOffice and LibreOffice if the legacy file format is maintained.

Based on information from FilExt.com, these files are tailored for complex document structures and should be edited with compatible office applications.

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.

Associated MIME types

FAQs

How do I open an SDW file on Windows or Mac?

The most reliable way to open an SDW file is using LibreOffice Writer or Apache OpenOffice. These suites are the modern successors to StarOffice and maintain backward compatibility for opening legacy StarWriter documents.

Can I convert an SDW file to Microsoft Word or PDF?

Yes, once you open the file in LibreOffice or OpenOffice, you can use the File > Save As menu to convert it to Microsoft Word (.docx) or OpenDocument Text (.odt). You can also select Export as PDF to create a non-editable version.

What is an SDW file?

An SDW file is primarily a text document created by the legacy StarOffice Writer software. It stores formatted text, images, and layout information in a binary format associated with the MIME type application/vnd.stardivision.writer.

Why can't I open my SDW file in Microsoft Word?

Microsoft Word does not natively support the proprietary StarOffice binary format. You must use a converter or open the file in LibreOffice first to save it in a format Word can understand, such as DOCX or RTF.

Are there other formats that use the .sdw extension?

Yes, while rare, the extension can be used for ESRI World Files (image coordinate data), which are plain text. It may also appear as an AmiDraw vector drawing, often identified generically as application/octet-stream.

How do I identify if my SDW file is a document or an image map?

Try opening the file in a basic text editor like Notepad. If you see readable numbers describing coordinates, it is likely an ESRI World File; if you see garbled binary code, it is likely a StarOffice document.

What is the correct MIME type for serving SDW files?

For StarOffice documents, the correct MIME type is application/vnd.stardivision.writer. You can verify specific configuration details at mime-type.com.

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.
