What's the difference between ISO and ZIP?
expand_more
ISO (ISO 9660 Disc Image) is best for creating exact sector-by-sector copies of cds, dvds, and blu-ray discs for backup and distribution. ZIP (ZIP Archive) is best for compressing and bundling files for sharing, with built-in support on every major operating system. Key tradeoff: ISO's advantage is bit-perfect disc image that preserves the exact filesystem structure, boot sectors, and partition layout of the original media, while ZIP's advantage is native os support on windows, macos, and linux — no third-party software needed to create or extract.
