What is a CD file?
The .cd file extension is used for an ISO file format that was developed for older disk image creation programs in Windows PCs. These CD disk images are in binary format and are also 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 The Philips / Optlmage's Master software is an old and outdated disk image creation tool that can be used to generate these .cd files.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 in the copied CD disks. A .cd file can be mounted unto a virtual drive so as to access and open the files and folders inside the CD disk image. These virtual drives are programs that are designed to simulate the functions of optical CD drives, and these are also called CD drive emulators.These .cd files can be opened using ISO Buster, which is a disk image authoring program for Windows PCs. This software can also be used to edit and access the files and folders inside a CD disk image. The ISO buster application can also be used to export these .cd files to other more standard disk image formats.
