Document created by ConceptDraw PRO, an application used to create business drawings; contains a drawing, such as a conceptual diagram or flowchart, along with any shapes, charts, diagrams, and people that have been inserted by the user.

CDDZ files may also contain program code written in a scripting language called ConceptDraw Basic, which allows users to automatically manipulate drawing objects. It is commonly used to automate repetitive tasks. CDDZ files can be converted to and from .VSD and .VSDX files and can also be exported to .PDF and .PPT files. ConceptDraw is available in Office, MINDMAP, PRO, and PROJECT editions, but only the PRO version opens and saves CDDZ files. NOTE: The CDDZ file was introduced with version 10 of CS Odessa ConceptDraw PRO. Version 9 and earlier use the .CDD file extension for saving documents.
