StarOffice Drawing (.sxd)
The SXD file extension stands for StarOffice Drawing and is associated with the StarOffice Draw program, now known as OpenOffice Draw. It is a vector graphics format used for creating and storing technical illustrations, including drawings, charts, and other visual data. Originally developed by Oracle, SXD files save vector elements such as points, lines, and curves, and may also include raster graphics. The format has since been integrated into the OpenDocument standard used by OpenOffice and Apache OpenOffice.
