StarOffice XML Global Document (.sxg)
The SXG file extension stands for StarOffice XML Global Document. It is used in Apache OpenOffice to manage large documents by linking multiple smaller documents, known as Master Documents. This format enhances performance and manageability, making it ideal for extensive projects like books and long reports. Originally developed by Sun Microsystems (later acquired by Oracle Corporation), SXG files have played a significant role in document management within the suite.
