Description
The SDG file type is associated with StarOffice Gallery, a component of StarOffice Suite, which was an office suite developed by Sun Microsystems. It is primarily used to store collections of images, graphics, and themes that can be inserted into documents and presentations created within the StarOffice suite. SDG files serve as libraries or galleries from which users can easily access and manage pre-defined or custom multimedia content to enhance their documents. Although StarOffice has evolved into OpenOffice and later LibreOffice, SDG files represent a legacy format for organizing and utilizing graphical resources in office documents.
