About .sdd Files
SDD files are files used by StarOffice applications.
They often represent presentation files from StarOffice Impress. However, the SDD extension is also linked to other document types in the StarOffice suite.
- Presentations: Files using application/vnd.stardivision.impress or application/vnd.stardivision.impress-packed are designed for slide shows.
- Spreadsheets: Files with application/vnd.stardivision.calc handle numerical data.
- Charts and Drawings: Files marked as application/vnd.stardivision.chart or application/vnd.stardivision.draw support graphic work.
- Text Documents: Files with application/vnd.stardivision.writer or application/vnd.stardivision.writer-global are used for word processing.
- Email and Math: Files using application/vnd.stardivision.mail or application/vnd.stardivision.math manage messages or equations.
They are binary files. They require compatible software to open and edit, such as StarOffice, OpenOffice, or LibreOffice.
Based on information from FilExt.com, SDD files serve as a container for several office document types.
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 SDD file?
An SDD file is primarily a presentation file created by StarOffice Impress, the predecessor to modern tools like OpenOffice Impress. While usually containing slides, the extension was sometimes used for other StarDivision document types, including spreadsheets and drawings.
How do I open an SDD file?
You can open SDD files using free, open-source office suites like LibreOffice or Apache OpenOffice. These programs maintain backward compatibility with legacy StarOffice formats. Simply launch the application and use File > Open to view your document.
Can I convert SDD files to PowerPoint format?
Yes, once you open the file in LibreOffice or OpenOffice, you can convert it. Select File > Save As and choose a modern format like Microsoft PowerPoint (.pptx) or OpenDocument Presentation (.odp) to ensure future compatibility.
What MIME type is used for SDD presentation files?
SDD presentation files are typically identified by the MIME type application/vnd.stardivision.impress. However, because the extension covers various StarOffice components, you might also encounter types like application/vnd.stardivision.draw or application/vnd.stardivision.calc on mime-type.com.
Why can't I open my SDD file in Microsoft Office?
Microsoft Office (Word, PowerPoint) does not natively support the legacy StarDivision binary formats. You must first open the file in a compatible suite like LibreOffice and save it as a standard Microsoft format (.doc or .ppt).
Are SDD files still used today?
No, the SDD format is obsolete and was replaced by the OpenDocument standard (such as .odp for presentations) in the early 2000s. It is highly recommended to convert these files to modern formats to prevent data loss.
What if my SDD file is not a presentation?
If the file does not open in an office suite, it might be a rare Studio Screen Designer data file commonly associated with CBM programming. These are binary files often identified as application/octet-stream and require specific legacy software to view.
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.
