An ISO image is a sector-by-sector copy of an optical disc (CD, DVD, Blu-ray), adhering to the ISO 9660 standard (and its extensions like Joliet or UDF). Each sector is typically 2,048 bytes (or 2,352 bytes for raw CD sectors). While perfect for exact duplication and mounting, ISOs are uncompressed. A full DVD-5 ISO consumes 4.7 GB of storage, even if much of that data is padding or redundant files.
