A .cgm extension is used by CAD (Computer Aided Design) software for its computer graphics metafile format. The .cgm file extension format enables interchange of graphical data for the computer representation of 2D graphics that are independent of a specific device, platform, system or application. The CGM file format is a universally accepted format for text, raster graphics and 2D vector graphics. The CGM format files are widely used by aviation, engineering and other applications related to the technical field.
The PPT format is a proprietary binary file format developed by Microsoft. It is mostly associated with Microsoft office PowerPoint, a closed source slide show presentation application. In Microsoft PowerPoint 2007 onwards, the .ppt filename extension format was superseded by the .pptx format which is part of the Office Open XML specification. Documents to be saved in the .ppt format are saved as PowerPoint 97, 2003 presentations.

A .cgm extension file format is compatible with any operating system. These are vector graphics format files that can support three encoding methods. One of these methods is the clear text encoding that allows reading and modification of a file using a text editor.
The ppt format uses Microsoft's OLE 2 compound document file format. It contains a hierarchical structure of storage and streams broken down to a user stream, PowerPoint document stream, pictures stream, an optional stream, and custom XML data stream. Actual content is represented as slide containers within the document stream. The format allows the inclusion of external objects such as pictures, sounds, and movies into one presentation.
