How to Open a .cdm File

A file with the extension ".cdm" is a disc image containing the contents of a CD or DVD. The ".cdm" format is a proprietary data storage system used by NTI Media Maker software. Using the appropriate program, you can open a ".cdm" file and view its contents, modify an existing ".cdm" file or burn an image to a blank disc. Although NTI Media Maker is a commercial product, you can download a free trial that remains functional for 30 days.
