File saved by SmartDraw, a professional diagramming program; contains a collection of SmartDraw files; used for saving groups of files together, such as .SDR files and images; also used for maintaining reference links to local files and hyperlinks to remote files. Collection packages are archives of Collections, which are directories that contain SmartDraw file assets. To first create a Collection, select the Save As... → SmartDraw Document (SDR) option from the SmartDraw application menu, and then choose "-Create New Collection..." from the "Save In Collection" drop down menu. The directory that is created now contains collection files for this drawing. Once operating within a Collection, you can export a Collection Package by selecting the SmartDraw menu and choosing Collection → Export Collection. Similarly, to import a Collection Package, select Collection → Import Collection from the SmartDraw application menu.
