Files with CSD file extension typically contain 3D scenes created using Clip Studio Paint, a software for creating 2D and 3D comic book models and characters. Contents of a CSD file created by Clip Studio Paint can range from 3D scenery, buildings, textures, to models of comic book characters. CSD file extension is also used to store game backup data created using Steam, a web platform for downloading and managing valve games. Some CSD files are based on Compound Document Format which is a standard for storing image and text files in highly compressed documents that can be opened with CSD Reader. CSD extension is also used to save MSDS Safety Data Sheet databases created using EH&S or DMS, hazard communication and document management software. A special embroidery format used by Poem, Singer EU and many other stitching machines uses CSD extension to store embroidery data.
