The Easy CD Creator Image (CIF) is a proprietary disc image format originally developed by Adaptec and subsequently managed by Roxio. It serves as a structural container for optical disc data, allowing users to archive, duplicate, or mount virtual CD and DVD media. Although now considered a legacy format superseded by the ISO standard, CIF files are generally safe as they consist of static disc data and lack mechanisms for code execution.
