The file extension CCD marks the CloneCD description files. CloneCD is a copying software that is controversial in Germany because of the possibility of copying copy-protected material. The developer Elaborate Bytes has ceased sales.
When copying a disk, CloneCD creates, for example, an iso file or a CCD file, depending on the mode used. In the CCD file are just metadata, the actual data of the disk are stored in an img file of the same name. (Often there is also a sub file).
CCD can also be burned onto an optical disk with the accompanying img file with CloneCD. In addition, a CCD file can also be 'mounted' by various virtual CD / DVD programs, provided that the img file is available. This means that the CD will be made available as a virtual drive. Special software that can convert the CCD and img files into another format also exists. These are subject to restrictions.

It is possible that although a compatible program has been installed on user’s system, it is not used by the system to open it. This may happen because no default application was associated with this type of files. To associate CCD files with given application, select "Open with" from drop-down menu (accessed by right-clicking on the file). Then select from the list the program or application you want to be used to open this type of file. If the Virtual CD applications is not on the list, select "Browse" option in order to manually locate the directory where Virtual CD has been installed.
Sometimes problems with opening CCD files may not lie with the application itself, but can arise due to other causes, such as:
