What is an .CGM file?

.CGM is Computer Graphics Metafile

Vector graphics format designed to support the needs of many graphics applications; originally used for clip art libraries, but newer revisions (based on the ISO/IEC 8632 standard) are now commonly used for CAD drawings.

CGM files are encoded using one of three different methods:

  • Binary encoding - Standard file encoding that enables software programs to read the file quickly and efficiently.
  • Character-based encoding - Produces the smallest possible file size, which saves disk space and allows for faster data transfers.
  • Clear-text encoding - Allows users to read and understand the contents of the file and modify the file using a basic text editor.
