Are you having problems opening a CD file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your CD files.

What is a CD file?

CD files have multiple uses, and CD-i OptImage CD Disk Image is one of them. Read more about the other uses further down the page.

CD-i OptImage CD Disk Image

The .cd file extension is used for an ISO file format developed for older disk image creation programs on Windows PCs. These CD images are in binary form and are called Philips / Optlmage's Master tool files.

The Philips / Optlmage's Master software is an old and outdated disk image creation tool that can be used to generate these .cd files. This software was designed for computers that run on older Microsoft Windows platforms.

These CD files contain directories, sub-directories, and files that are exact copies of the folders and files on the copied CDs.

A .cd file can be mounted as a virtual drive to access and open the files and folders inside the CD copy without having the original CD in the CD drive. These virtual drives are programs that are designed to simulate the functions of optical CD drives, and these are also called CD drive emulators.
