Why convert ISO to ZIP?
An ISO (ISO 9660 / UDF) is a binary disc image containing a complete file system, directory tree, and optionally a boot record. A ZIP is a compressed archive of individual files. Placing an ISO inside a ZIP merely wraps the binary image in a compression layer - the ISO inside remains intact and unchanged. Re-packaging the ISO's contents as a ZIP would require extracting every file from the disc image and archiving them separately, which is extraction, not conversion.

- Adding an ISO to a ZIP gains almost no space savings because ISO content is already uncompressed binary data; ZIP compression on disc images is negligible.
- To access files inside an ISO without conversion, mount it directly - on Windows 8 and later, right-click the
.isoand choose Mount. - If the ISO is an OS installer, use a dedicated tool to write it to a USB drive rather than archiving it.
