Magic ISO Maker

The tool converts a source directory into a standards-compliant disc image. It supports ISO9660 with Joliet/Rock Ridge and optional UDF, enabling cross-platform compatibility and large-file handling. Conceptually, it assembles filesystem tables, applies metadata, and writes blocks to a single ISO file. It can embed a boot catalog when a bootable option is requested, producing installation or recovery media suitable for virtualization or physical deployment. Beneficiaries include IT admins, software developers, system integrators, and archival specialists who require predictable, verifiable media. Core features include choosing the target filesystem, setting a volume label, optionally enabling bootable media with a boot loader, and generating a SHA-256 checksum for post-creation validation. The tool yields the output ISO path and size, along with a checksum for integrity checks. Its differentiators are strict adherence to ISO standards, robust error handling, support for large files via UDF, and built-in validation without external dependencies. Typical use cases are OS installer ISO creation, software distribution media, offline backups, and archival imports for virtualization environments. Algorithms: Directory traversal builds a file list; filesystem descriptors are generated according to the chosen standard; directory and file records are allocated; bootable descriptors are added if requested; and a final checksum is computed. Outputs include the ISO file path, size, and SHA-256 hash for verification. The design favors predictability, deterministic outputs, and reproducible results across platforms.
