A CloneCD Control File is a text descriptor with the extension .ccd used by CloneCD to store the subcode data of a CD/DVD image. These files need to be combined with an image file (usually with .img extension) to be burned. It may also come with a subchannel file (usually .sub).{{cite web | url = http://www.slysoft.com/en/i-heard-a-clonecd-image-consists-of-three-files-is-faq.20.330.html | title = SlySoft CloneCD FAQ | archive-url = https://web.archive.org/web/20131029200636/http://www.slysoft.com/en/i-heard-a-clonecd-image-consists-of-three-files-is-faq.20.330.html | archive-date = 2013-10-29 | publisher = SlySoft | url-status = dead}}{{cite web | url = https://www.afterdawn.com/glossary/file_extension.cfm/ccd | title = .ccd | website = AfterDawn Glossary }}
The .ccd extension can be used directly by first-party disc emulator Virtual CloneDrive. It can also be mounted with third-party virtual drives such as Daemon Tools and Alcohol 120%.
The command line Linux application ccd2iso is available to convert ISO9660-compliant CCD/IMG files to an ISO image. The GNU Project's ccd2cue can convert a CCD file to a cue sheet.{{cite web | url = https://www.gnu.org/software/ccd2cue/ | title = GNU ccd2cue - CCD sheet to CUE sheet converter | website = GNU Project | publisher = Free Software Foundation | orig-year = 2013 | date = 2015-03-13}}
The CUE/BIN and MDS/MDF formats have a similar structure to the CCD/IMG format, containing both a raw disc image along with a descriptor file.{{Cite web |last=Umar |first=Muhammad |date=2021-08-06 |title=CCD - CloneCD Control File |url=https://docs.fileformat.com/disc-and-media/ccd/ |access-date=2024-12-30 |website=docs.fileformat.com |language=en}}
The CloneCD CCD/IMG/SUB format is one of the few formats besides Nero's NRG, BIN/CUE and Alcohol 120%'s MDF/MDS disc image formats to support Mixed Mode CDs which contain audio CD tracks, as well as data tracks.
